[0019] Some embodiments of this disclosure, illustrating all its features, will now be discussed in detail. The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items. It must also be noted that as used herein and in the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Although any arm-rest assembly for passenger of a vehicle and, similar or equivalent to those described herein may be used in the practice or testing of embodiments of the present disclosure, the exemplary, arm-rest assembly for passenger of a vehicle is now described.
[0020] Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. However, one of ordinary skill in the art will readily recognize that the present disclosure is not intended to be limited to the embodiments described but is to be accorded the widest scope consist in this regard, in a generic sense.
[0021] The present invention discloses a multidirectional collapsible arm rest assembly. The multidirectional collapsible arm rest assembly is provided with plurality of components (30), (32), (38) and (40) connected with each other through atleast one of the mechanism for providing relative motion between them. The said mechanism can be one or more of scissor type mechanism, slide up and lock mechanism, a sliding mechanism, pivot mechanism, lock and spring mechanism, adjustable mechanism, telescopic mechanism, screw mechanism. The multidirectional collapsible arm rest assembly is configured to be selectively opened and locked at a desired position in X, Y and Z direction.
[0022] Figure 1 illustrating the arm-rest assembly in complete open condition. All X, Y and Z direction adjustment are independent to each other and driver can adjust arm rest by combining all three direction movement and setting it to his desired comfortable position. The arm-rest is completely collapsible. The arm-rest adjusting mechanism has no positive locking, i.e. the arm-rest opening-closing operation is hustle free and can easily be opened and closed without any tools or hardware.
[0023] As per one embodiment the arm rest assembly (2) is movable in Z direction by slide up and lock mechanism (34). As per one embodiment the arm rest assembly (2) is movable in X direction by sliding mechanism (28). As per one embodiment the arm rest assembly (2) is movable in Y direction by scissor mechanism (16). However, the type mechanism to be used for moving the armrest assembly in X, Y and Z direction is configured to vary depending on the variation in movement of the components (30), (32), (38) and (40) and directions.
[0024] Figure 2 illustrates adjustment of arm-rest assembly in Y direction. As per one embodiment of the invention the Y-direction mechanism works on simple scissor type mechanism (16). One end of the scissor mechanism (16) is configured to be fitted on the armrest bottom assembly (30) and other end of scissor mechanism is fitted on a block (32) configured for mounting arm rest assembly through scissor mechanism to door panel. The scissor end mounted on the said block (32) are configured to be pivotally secured whereas the other end mounted on the armrest has one end pivotally secured while other end is sliding end (22). The sliding end (22) is configured with sliding and locking mechanism (48) comprising of grooves (18) to lock the armrest at different positions. The driver can adjust the distance accordingly. In home position, arm rest forms an integral one piece assembly with the door trim and is visible as a part of door trim and the sliding end (22) will be in end most groove (18). The driver can pull out arm rest and it will get locked in the next groove (18). Accordingly, driver can adjust his arm rest (2) at multiple locations in Y direction. The locking of the sliding end (22) in the sliding and locking mechanism (48) is not a positive locking hence, the driver can simply push the arm rest (2) inside and it will get back integrated to its home position.
[0025] Figure 3 illustrates adjustment of arm-rest assembly in Z direction. As per one embodiment the Z-direction mechanism works on simple slide up and lock mechanism (34). The arm- rest is split in 02 parts. The bottom part (40) is fixed and has (fixed) scissor mechanism (16) ends. Whereas, upper part (38) can be split and pulled up at specific height. Both parts are connected with each other with two rods. One rod (6) is for supporting and sliding while other rod (36) is also used for sliding and has locking mechanism and grooves (4) in it. The locking mechanism is a simple spring loaded mechanism. When button (8) is pressed, lock is released and the height is adjusted by pulling the arm-rest. The grooves (4) are provided on the rod (36); so on every groove (4) lock gets engaged. The driver adjusts the height of arm rest (2) accordingly.
[0026] Figure 4 illustrates adjustment of arm-rest assembly in X direction. As per one embodiment the movement of arm rest assembly (2) in X-direction mechanism works on simple sliding mechanism (28). The sliding mechanism (28) forms an integral part of armrest bottom assembly (30). The sliding mechanism (28) is T shaped and is configured to move in the corresponding groove provided on arm rest lower part (40) is mounted on fitted in between sliding and locking mechanism (48) and slide-up and lock mechanism (34). The top sliding mechanism (28) slides freely in front and rear directions over grooves that are provided in arm rest bottom assembly (30). The height adjuster rods do not interfere with the sliding mechanism (28).
[0027] Further, the invention can be used, but not limited to, in the following applications.
[0028] The multidirectional collapsible armrest assembly (2) comprises various mechanisms configured of one or more of scissor type mechanism, slide up and lock mechanism, a sliding mechanism, pivot mechanism, lock and spring mechanism, adjustable mechanism, telescopic mechanism, screw mechanism and alike mechanism to provide relative motion between a pair of plurality of components. The armrest assembly (2) is configured from an armrest bottom assembly (30), a block (32), an armrest upper part (38) and an armrest lower part (40). The armrest assembly is configured to be selectively extended and locked at a desired position in alteast one of the X,Y and Z direction. The armrest assembly (2) is provided with block (32) configured for mounting one end of a scissor mechanism (16) and other end of the scissor mechanism is configured to be mounted on the armrest bottom assembly (30) for movement of armrest assembly (2) in Y direction. The both ends of one side of the scissor mechanism (16) are configured to be pivotally secured on said block (32) and one end of other side is configured to be pivotally mounted on the armrest bottom assembly (30) and other end is a sliding end (22). The sliding end (22) of scissor mechanism (16) is configured with a sliding and locking mechanism (48) provided with grooves (18) to lock the armrest at different selective positions as required by the occupant. The arm rest assembly (2) is configured with a slide up and lock mechanism (34) constituted with lower part (40) and upper part (38) wherein, the upper part (38) is adapted for lifting and securing the armrest assembly (2) at a desired height in Z direction. The armrest assembly (2) with upper part (38) and lower part (40) is provided with upper part (38) and lower part (40) configured to be slidably connected to each other through plurality of rods wherein, atleast one rod is provided with a locking mechanism. The armrest assembly (2) is provided with a sliding mechanism (28) configured for slidably mounting the lower part (40) on sliding mechanism (28) to slide and lock the armrest assembly (2) at desired position in X direction.
[0029] Exemplary embodiments discussed above may provide certain advantages. Though not required to practice aspects of the disclosure, these advantages may include the following:
[0030] Some embodiments of the present subject matter provide arm-rest adjustable in X, Y and Z direction to passengers in vehicles.
