A backrest frame is provided with a cushion plate of one substantially square plate form positioned behind the waist from the upper part of the back of a vehicle seat occupant, movably back and forth by way of a plurality of upper and lower parallel seat springs, one end of either one of a pair of right and left seat springs of the plurality of upper and lower parallel seat springs is connected to a pair of lower link mechanisms provided rotatably on the backrest frame, and a rear end collision sensor is formed by the cushion plate between the seat springs for moving a headrest forward, and a coupling part of the other end of the seat spring is directly attached to the lower link mechanism.

Claims28

Dependent claims

A vehicle seat comprising:

a backrest frame having right and left side frames;
a headrest for supporting a head of a seat occupant that is mounted to the backrest frame;
a rear-end collision detector mounted to the backrest frame and disposed in a position behind the seat occupant, wherein the rear-end collision detector detects rearward movement of the seat occupant;
and
a seat cushion provided in front of the rear-end collision detector;
wherein:
the rear-end collision detector is supported to the backrest frame via a rotary member mounted to the backrest frame and a connecting member connected to the rotary member;
the rear-end collision detector acts such that the rearward movement of the rear-end collision detector moves the rotary member to reduce a distance between the head of the seat occupant and the headrest;
a concave portion is formed at an end portion of the seat cushion in a right-to-left direction;
and
an end portion of the connecting member is accommodated in the concave portion.
