Title: Seats for vehicles

Description:
FIELD OF THE INVENTION 
     The present invention relates to a seat for vehicles and the seat includes a net and a seat frame, the net is securely connected between first frame and second frame so as to provide good ventilation. 
     BACKGROUND OF THE INVENTION 
     The conventional vehicle seats such as bicycle seats or autobike seats, generally includes a seat pad and/or a backrest so that the users sit on the seat pad to operate the vehicle. Most of the seat pads and backrests are made by a foam pad wrapped with a plastic outer layer. The conventional seats can provide basic flexible and comfortable feature, some outer layers are made by air-permeable material or includes gel. Nevertheless, the conventional seats are complained to have less ventilation ability and the users feel not comfortable when setting for a period of time. 
     Some vehicle seats have holes to enhance the ventilation and some have a layer of gel which is soft and flexible, but most of the conventional seats do not have satisfied ventilation. The seats of autobikes and cars have similar problems although cars have air condition systems to cool the interior temperature in the cars, the outer layer of the seats directly contacts the user&#39;s body so that the heat cannot be removed properly. 
     The present invention intends to provide a vehicle seat which is composed of a net and a frame, the net is securely connected to the frame so as to provide proper ventilation and the net is strong and flexible to support heavy load. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a vehicle seat which comprises a frame and a net, the frame is composed of a first frame and a second frame, and the net has its periphery clamped between the first and second frames. 
     The primary object of the present invention is to provide a vehicle seat which comprises a net connected to a frame, the net is flexible so as to provide the users a comfortable sitting experience. 
     Another object of the present invention is to provide a vehicle seat wherein the net includes apertures which provide good ventilation. 
     The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
