Claim 1
Independent Claim
134 words
A seat for a vehicle, said seat comprising a seat part supported in a first frame, and a back part resiliently supported in a second frame connected to and supported by said first frame, the said seat part being supported at its rear portion by said back part and at its front portion by a pair of rearwardly extending arms mounted at their forward ends to said first frame and at their rearward ends to said seat part at points spaced from the front edge of said seat part, said arms being rigidly joined to each other at their rearward ends by an elongated bar whereby downward pressure applied to one arm will be transmitted to the other, and resilient means urging the front edge of said seat part upwardly relative to said frame.
