Abstract
A vehicle seat comprises a seat back frame having a pair of side frames, a seat spring mounted between the side frames, a single plate-shaped flexible cushion plate mounted to the seat spring, a seat back cushion provided in front of the cushion plate, a single plate-shaped flexible auxiliary plate mounted on the cushion plate. The auxiliary plate is located between the cushion plate and the seat back cushion. The auxiliary plate pushes the seat back cushion to the front by being forwardly bent in response to an operation member. A collision detector is located on the rear side of the cushion plate having a predetermined distance there between.

A vehicle seat comprising:
- a seat back frame having right and left side frames;
- a headrest forwardly movably mounted to the seat back frame;
- a rear-end collision detector mounted to the seat back frame, wherein the rear-end collision detector detects rearward movement of the seat occupant and moves rearward;
- and the rear-end collision detector is operatively connected to the headrest such that the rearward movement of the rear-end collision detector forwardly moves the headrest to support a head of a seat occupant;
- a respective support shaft mounted to each side frame;
- a link member mounted to the support shaft, wherein a lower portion of the link member is connected to the rear-end collision detector;
- a biasing member that biases the link member;
- a load receiving member for receiving a load from the seat occupant;
- and
- a wire spring coupled to each of the side frames at each of both ends of the wire spring;
- wherein at least a part of the load receiving member is positioned below the rear-end collision detector and supported by the wire spring, the side frame includes a wire spring engagement portion for engaging the end of the wire spring, and the wire spring engagement potion is positioned below a lower end of the link member.
