The present invention relates to a vehicle seat having a damper.

  Generally, a vehicle seat such as an automobile has a reclining function, and such a vehicle seat is configured such that a seat back can be turned with respect to a seat cushion. More specifically, the lower end of the seat back is pivotally attached to the rear end of the seat cushion in the front-rear direction of the seat via a reclining mechanism, and the seat back has a basic posture and the basic posture. The vehicle can be turned at least between a posture and a rearward inclined posture inclined rearward of the seat. Further, in a vehicle seat, the seat back may be configured to be able to return to a basic posture from a rearward inclined posture by an urging force of an elastic body such as a spring. When returning the seat back, it is required to prevent the seat back from vigorously hitting the occupant sitting on the vehicle seat.

  Therefore, the reclining mechanism of the vehicle seat is provided with a damper such as an oil damper configured to be able to generate a damping force with respect to the turning of the seatback, in particular, the turning of the seatback from the backward inclined posture toward the basic posture. Sometimes. The damper includes a damper fixing member attached to a main body of the reclining mechanism, and a damper movable member configured to be capable of pivoting around the pivot axis of the damper with respect to the damper fixing member while generating the damping force. The movable damper member is connected to the seat back.

  As an example of such a vehicle seat, a support member (movable hinge plate) is attached to a seat back in a state of being spaced from a turning axis of a damper (rotary oil damper) and attached to a damper movable member (outer) of the damper. A connecting portion (convex portion) is formed so as to protrude from the peripheral portion toward the supporting member, and the connecting portion is rigidly fixed to the supporting member to rigidly connect the damper movable member and the seat back. (See, for example, Patent Document 1).
