Abstract
A vehicle seat comprises a headrest mounted on the seatback frame so as to be movable in a front-and-back direction, a cushion plate mounted on the seatback frame, and a collision detector provided at back side of cushion plate. The headrest is connected to the collision detector by way of a active headrest mechanism. When the collision detector is moved backward, the headrest is moved forward. A space part is formed between an upper edge of the cushion plate and an upper frame of the seatback frame. The space part is enlarged by forming the upper frame by a pipe frame.

A vehicle seat comprising:
- a seatback frame;
- a headrest mounted on the seatback frame so as to be movable in a front-and-back direction by an active headrest mechanism;
- a collision detector provided on the seatback frame to detect backward movement of a lumbar part of a seat occupant when a rear-end collision occurs;
- wherein the collision detector and the active headrest mechanism is connected with each other by way of a link mechanism so that the headrest is moved forward by the backward movement of the collision detector to support a head of the seat occupant;
- wherein at least an upper frame of the seatback frame in which the active headrest mechanism is provided is formed from a cylindrical member, thereby forming a space part surrounded by the upper frame and side frames on left and right sides above the seatback frame.
