FIELD OF THE INVENTION

Present invention generally relates to a seat assembly for a two wheeled vehicle.

BACKGROUND OF THE INVENTION

In two wheeler industry, seat for vehicles has mainly two components viz. seat foam and seat cover. Material used for these parts is generally poly-urethane and majority of polyurethane variants absorbs heat and hence temperature of the seat increases especially when the vehicle seat is in close contact with human body & when it is exposed to sunlight.

Due to temperature increase, use of such seats become very difficult and the rider remains uncomfortable during driving because of skin burning sensation.

In view of above mentioned issue a solution is required for described problem.

SUMMARY OF THE INVENTION

Main objective of the present invention is to provide a seat assembly having a cooling element having cooling and damping characteristics. Said cooling element is moulded with the seat foam at one or more locations such that heat absorbed by seat foam does not affect rider skin directly.

Another objective of this invention is to provide a seat assembly where seat foam, cooling element and the seat cover are integrated with each other such that the cooling element may or may not be exposed to the environment and hence facilitate a heat less ride for the vehicle user.

Further, as one more objective of the present invention is providing a seat cover which is integrated with the cooling element either by moulding or stitching or pressing or any other means. In this cover, the cooling element is exposed to environment and provides good aesthetic appearance and riding comfort.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will become more fully understood from the detailed description given herein below and the accompanying drawing which is incorporated in and constitute embodiments of the invention. Given Drawings illustrates several aspects of the invention and together with a description of the embodiments serve to explain the principles of the invention. A brief description of the drawing is as follows:

Figure 1 and Figure 2 are describing the manufacturing process of the claimed seat assembly of the two wheeled vehicle.

Figure 3 to Figure 9 are depicting embodiments of the claimed seat assembly of the two wheeled vehicle.

DETAILED DESCRIPTION OF THE INVENTION

The embodiments disclosed below are not intended to be exhaustive or to limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described for enablement purpose of the invention. The invention may have application to all types of vehicles. The scope of the invention is entirely based upon the claims provided.

Reference is made to Figure 1 to Figure 9 to describe manufacturing process for claimed seat assembly 106 and the embodiments of said seat assembly 106. A cover surface layer 101 is placed or applied inside the moulding unit 103 placed over a base 102.

This cover surface layer 101 is applied in case of a seat assembly 106 having seat cover 107, seat foam 105 and the cooling element 100 integrated with each other. If the seat assembly 106 has separate seat cover 107 then the cover surface layer 101 is replaced by an anti-sticking element.

Further, a cooling element 100 is placed inside the moulding unit 103 at one or more places. This cooling element 100 over the cover surface layer 101 is covered with a layer of foam 105 through the pouring head 104.

Further seat assembly 106 is described (Figure 3 to Figure 9) where a cooling element 100 is moulded in the seat foam 105 (specifically Figure 3 and Figure 4) at one or more locations (specifically Figure 8 and Figure 9) so that the body contact area for vehicle rider is minimum with direct seat foam 105 or the seat cover 107.

The hardness ratio of said cooling element 100 and the seat foam 105 always remains 0.5:5 in order to provide better comfort to the vehicle user. The units for hardness typically can be in kgf for the polyurethane foam & Shore A & Shore OO (durometer) for the cooling element. Further, the thickness of mentioned cooling element 100 varies between 2 mm to 25 mm as per the requirement of the vehicle and user.

Cooling element 100 can be of any shape, size (Figure 7) and can be fixed or moulded at as many locations over the vehicle seat 106. This cooling element 100 and the seat foam 105 are different variants of polyurethane.

The seat cover 107 can be of any material and is fixed with the cooling element 100 or the seat foam 105 either by spraying seat foam layer 101 inside moulding cavity 103 or by pouring through a pouring head 104 or by stitching or by any other possible means.

Said seat assembly 106, further can have a separate seat cover 107 with a cooling element 100 at one or more positions. In this case the cooling element 100 and the seat cover 107 are integrated either by RF (radio frequency) welding or by pasting, mending or by stitching.
