[0027] FIG. 1 illustrates a seat (100) of a vehicle for providing massaging perception to an occupant, according to embodiments as disclosed herein. The vehicle seat (100) includes a back assembly (102), and a seat assembly (104) connected the back assembly (102). The back assembly (102) and the seat assembly (104) includes vibrating elements (1081-n) connected to a motor (110). The vibrating elements (1081-n) in the back assembly (102) and the seat assembly (104) vibrates to provide a massaging perception to an occupant of the seat (100).
[0028] The vehicle is not shown in the FIG. 1 and may be, for example, a passenger vehicle, such as a car, a commercial vehicle, such as a bus, or the like. The seat (100) may be the one on which a driver, a co-driver, or another passenger of the vehicle may sit.
[0029] In an embodiment, the back assembly (102) is divided into multiple regions (1061-n) each of which comprises at least one vibrating element of the plurality of vibrating elements (1081-n) to provide the massaging perception to corresponding back body part of the occupant of the seat (100), and a centre region (111) is surrounded by the multiple regions (1061-n). The centre region (111) includes the motor (110) connected to the at least one vibrating element disposed in each region of the multiple regions (1061-n). In an embodiment, the back assembly (102) comprises a plurality of horizontal rods (1121-n) and a plurality of vertical rods (1141-n) arranged in the form of a grid to link the motor (110) with each region of the plurality of regions (1061-n) and the centre region (111) of the back assembly (102). The motor (110) generates vibration signals which are transmitted to the plurality of vibrating elements (1081-n) through the plurality of horizontal rods (1121-n) and the plurality of vertical rods (1141-n).

[0030] In an embodiment, the vibrating elements (1081-n) is springs and/or local vibration components.
[0031] Similarly, the seat assembly (104) is divided into multiple regions (1061-n) each of which comprises at least one vibrating element of the plurality of vibrating elements (1081-n) to provide the massaging perception to corresponding lower body part of the occupant of the seat (100), and a centre region (111) is surrounded by the multiple regions (1061-n). The centre region (111) includes the motor (110) connected to the at least one vibrating element disposed in each region of the multiple regions (1061-n). In an embodiment, the seat assembly (104) comprises a plurality of horizontal rods (1121-n) and a plurality of vertical rods (1141-n) arranged in the form of a grid to link the motor (110) with each region of the plurality of regions (1061-n) and the centre region (111) of the seat assembly (104). The motor (110) generates vibration signals which are transmitted to the plurality of vibrating elements (1081-n) through the plurality of horizontal rods (1121-n) and the plurality of vertical rods (1141-n).
[0032] The motor 110 may be, for example, a direct current (DC) motor, and may be powered by a battery (not shown in FIG. 1) of the vehicle. The motor (110) may be made to vibrate and the vibration may be transferred to the springs 108 by a linkage mechanism that couples the body of the motor (110) with the vibrating elements (1081-n). The linkage mechanism may include the plurality of horizontal rods (1121-n) and the plurality of vertical rods (1141-n) arranged in the form of a grid.
[0033] FIG. 2 schematically illustrates vibrating elements in a plurality of regions (1061-n) and their coupling with the motor (110), according to embodiments as disclosed herein. To cause vibration of the motor (110), an imbalance may be created during rotation of the motor (110). In an embodiment, the motor (110) includes a mass (202) disposed on a shaft of the motor (110) to create an imbalance during rotation of the motor (110) to generate the vibration signals from the motor (110). The imbalance may be created, for example, by disposing the mass (202) on a shaft of the motor (110) offset from a centre of the shaft. As will be understood, a frequency of vibration of the motor (110) corresponds to a speed of rotation of the motor (110).

[0034] In an embodiment, the speed of rotation of the motor (110) is adjusted such that the frequency of vibration of the motor (110) may equal a natural frequency of a vibrating element. Accordingly, during vibration of the motor (110), the spring achieves resonance, and vibrates with a large amplitude. The vibration with large amplitude provides a massaging perception to the occupant of the seat. The massage may be perceived at a part of the occupant’s back that is directly over the resonating vibrating element.
[0035] In an embodiment, each vibrating element among the vibrating element (1081-n) may have a different natural frequency than the other springs. Further, the speed of the motor (110) may be adjusted such that the frequency of vibration of the motor (110) equals the natural frequency of one of the vibrating element (1081-n), thereby causing resonance of a particular spring and causing massaging perception on a part of the back of the occupant that is directly over the spring. For example, massage may be perceived on a part of the occupant’s back over a first spring (108-1) (e.g., right, upper back) by causing the first spring (108-1) to resonate (by causing the motor (110) to vibrate at the natural frequency of the first spring 108-1). The vibrating element that is to be made to resonate (and consequently the part of the back of the occupant on which massage is to be perceived) may be controlled by the occupant. To this end, a selection option (not shown in FIG. 1) may be provided on a dashboard (not shown in FIG. 1) of the vehicle. The selection option may be in the form of push buttons or virtual buttons on a touchscreen in the dashboard. Based on a selection made by the occupant, a controller (as shown in FIG. 5) may adjust the speed of the motor (110).
[0036] By providing vibrating elements (for example springs as shown in the FIG. 2) of various natural frequencies in the seat (100) and by causing the motor (110) to vibrate at natural frequency of one of the vibrating elements (108), massage may be perceived at a desired part of the occupant’s back. In an implementation, massage may be provided at more than one part of the occupant’s back, such as the parts over the first spring (108-1) and a second spring (108-2). To this end, the motor (110) may vibrate at natural frequencies of the springs corresponding to the parts of the occupant’s back in subsequent time slots. For example, if the part of the occupant’s back over the first spring (108-1) and the part of the occupant’s back over the second spring (108-2) are to perceive massage, the motor (110) may vibrate at the natural frequency of the first spring (108-1) for a first time period of, say, 10 seconds, and may vibrate at the

natural frequency of the second spring (108-2) for the next 10 seconds. In an example, the natural frequency of each of the springs (108) may be between 20 and 60 Hertz, as humans tend to perceive massage for vibrations ranging from 20 to 60 Hertz.
[0037] As will be appreciated, each of the springs 108 tends to vibrate for all frequencies of vibration of the motor (110), regardless of whether the frequency of vibration of the motor (110) matches with the natural frequency of that spring (although amplitude of vibration of the resonating spring tends to be much higher than that of the other springs). Thus, massage may be perceived at all parts of the occupant’s back for each vibration of the motor (110), with one part (corresponding to the resonating spring) perceiving more massage as compared to the remaining parts.
[0038] In the above description, the vibrating element is explained with reference to a spring. In some examples, springs may not be provided in regions of the seat (100), and other parts may be provided for vibrating, as will be explained below.
[0039] FIG. 3 illustrates the plurality of regions (1061-n) each having a local component for vibration, according to embodiments as disclosed herein. Similar to a spring in a region as explained with reference to FIGS. 1 and 2, each local component in a region may also have a natural frequency that is different than those of local components of other regions. Further, each local component may be coupled to the motor (110) by means of a linkage mechanism (not shown in the FIG. 3), similar to the linkage mechanism explained with reference to the FIG. 1. Accordingly, a local component resonates when the motor (110) vibrates with a frequency equal to that of the natural frequency of that local component. In an example, the local component may be a rib, rod, or the like. Further, the natural frequency of the local component may be adjusted to a particular value by adjusting its mass and stiffness. In an example, multiple local components having the same natural frequency may be provided in a region.
[0040] In an embodiment, both spring and local component having the same natural frequency may be provided in a region. Accordingly, both the spring and the local component resonate when the motor (110) vibrates at their natural frequency. As will be understood, the amplitude

of vibration of a region having both a spring and a local component resonating will be higher than that having only the spring or the local component resonating. Thus, a better massage is perceived by the occupant of the seat having both a spring and a local component in a region.
[0041] FIG. 4(a) illustrates massage perception provided by a combination of local component and spring of a region, according to an implementation of the present subject matter. Here, r1-r8 indicate eight frequencies of vibration of the motor (110), each of which equals the natural frequency of one combination of spring (S) and local component (L) of a particular region. The resonance of a spring (S) and local component (L) of a particular region causes a part of the occupant’s back over that region, such as upper back, middle back, or lower back to perceive massage.
[0042] FIG. 4(b) illustrates various parts of an occupant’s back that can perceive massage, according to an implementation of the present subject matter. As illustrated, the back of an occupant (402) may be divided into nine parts (4021-9). The parts (4021-4), and the parts (4026-9) may be resting over a region of the seat 100 having a combination of spring and local component (not shown in the FIG. 4(b)). Such parts may experience massage when the combination of the spring and local component resonate, as explained earlier. Such parts experience massage also when the combination of the spring and local component vibrate at a frequency other than their natural frequency, although the massage experienced may be lesser. The part (4025) may be resting over a region of the seat (100) having the motor (110), and may experience massage when the motor (110) vibrates.
[0043] Although the vibrating elements have been explained as being provided in the back assembly, similar configuration of vibration elements may be provided in the seat assembly (104) of the seat as well. Accordingly, massage may be provided also to the bottom part of the occupant of the seat.
[0044] The present subject matter increases comfort of an occupant of a seat of a vehicle, and prevents pain, soreness, or the like on the occupant’s back and bottom. By providing vibrating elements of different natural frequencies in various regions of the seat, and by selecting causing them to resonate, massage may be provided to various parts of the occupant’s back and bottom.

[0045] FIG. 5 illustrates a massage system (500) for providing massaging perception to an occupant of the seat (100). The massage system (500) includes the vehicle seat (100) comprising a back assembly (102) connected to a seat assembly (104). The back assembly (102) and the seat assembly (104) includes the plurality of vibrating elements (1081-n) connected to the motor (110) as described with respect to FIGS. 1-4. The massage system (500) includes a motor controller (500) disposed on a dashboard of the vehicle and is electrically connected to the motor (110). The plurality of vibrating elements (1081-n) in the back assembly (102) and the seat assembly (104) vibrates to provide a massaging perception to an occupant of the seat (100). A speed of the motor (110) is controlled using the motor controller (502) to control the vibrations from the vibrating elements (1081-n).
[0046] In an embodiment, control the speed of the motor (110) includes detect by the motor controller (502) an input from the occupant and control resonance and amplitude of the plurality of vibrating elements (1081-n) to restrict the vibrations from the vibrating elements (1081-n).
[0047] The vibrating element that is to be made to resonate (and consequently the part of the back of the occupant on which massage is to be perceived) is controlled by the occupant. To this end, a selection option (in form of motor controller (502)) may be provided on a dashboard (not shown in FIG. 5) of the vehicle. The selection option may be in the form of push buttons or virtual buttons on a touchscreen in the dashboard. Based on a selection made by the occupant, the motor controller (502) is used to adjust the speed of the motor (110).
[0048] The foregoing description of the specific implementations will so fully reveal the general nature of the implementations herein that others can, by applying current knowledge, readily modify and/or adapt for various applications without departing from the generic concept, and, therefore, such modifications and adaptations should and are intended to be comprehended within the meaning and range of equivalents of the disclosed implementations. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the implementations herein have been described in terms of preferred implementations, those skilled in the art will recognize that the implementations herein can be practiced with modification within the spirit and scope of the implementations as described herein.
