Abstract
A vehicle seat comprises a rectangular-shaped seat back frame having right and left side frames; a flexible plate member provided between the right and left side frames; a seat back cushion provided in front of the flexible plate member; a mechanism for pushing the seat back cushion to a front direction by forwardly protruding the flexible plate member that results from the flexible plate member being bent; a headrest for supporting a head of a seat occupant, wherein the headrest is forwardly movably connected to the right and left side frames via right and left link members; and a rear-end collision detecting plate disposed at a portion of the seat back frame behind the seat occupant, wherein the rear-end collision detecting plate detects rearward movement of the seat occupant.
Claims45
A vehicle seat comprising:
- a seat back frame having right and left side frames;
- a headrest 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 a seat occupant and moves rearward;
- and the rear-end collision detector acts such that the rearward movement of the rear-end collision detector reduces a distance between a head of the seat occupant and the headrest;
- a respective support shaft mounted to each side frame;
- a support member that supports the support shaft;
- a link member mounted to the support shaft;
- and
- a biasing member that biases the link member;
- wherein:
- a lower portion of the link member is connected to the rear-end collision detector;
- each of the side frames is provided with a front projecting wall inwardly projecting and integrally formed at a front end of the respective side frame, and a rear projecting wall inwardly projecting and integrally formed at a rear end of the respective side frame;
- each of the side frames comprises a lateral face, the lateral face comprising a concave portion that is indented or concave in a direction towards the other side frame;
- at least a part of the support member is attached to the concave portion;
- the concave portion is provided with an opening and a support member attachment portion for attaching the support member;
- and
