SEAT PAD FOR VEHICLE

A seat pad 1 for vehicles comprises a top part 2 corresponding to a seating section (under-hip section), an under-thigh section, and side bulging sections, and a bottom part 3 located on the underside of the top part 2. The top part 2 and the bottom part 3 are formed separately from each other and are connected to each other. The bottom part 3 is formed into the same configuration allowing commonization among different types of vehicles so that the seat pad can be partly commonized among various types and various grades of vehicles. A seat sensor 4 is disposed between the bottom part 3 and the top part 2.
