Claims

[Scope of utility model registration request]

In a headrest whose angle can be adjusted by tilting the headrest body with respect to the support stay,
A headrest frame is tiltably pivoted to the support stay via a substantially horizontal pivot shaft, a locking pawl is formed at an upper portion on the side of the support stay, and the headrest frame is locked in one direction; A tooth member having a tooth portion that engages with the locking pawl so that it can be crossed over in the opposite direction is pivotably supported around a substantially horizontal axis, and the tooth member is rotated in the locking direction of the locking pawl. a release engaging portion capable of being reversely biased in the opposite release direction, and engaging the tooth member and reversing it in the release direction when the locking pawl reaches the end of the tooth of the tooth member; , a return engaging portion that engages with the tooth member and reverses it in the locking direction of the locking claw when the locking claw returns to the vicinity of the starting end of the tooth member that has been reversed in the release direction; A headrest characterized by being provided on the stay side.
