Abstract
The present invention provides a tiltable headrest for a vehicle seat. The tiltable headrest comprises a hinge part for causing a headrest body to be supported by a support bar and for allowing the support bar to be rotated within a predetermined angle relative to a body support frame which supports the headrest body; and an auxiliary guide arrangement for surrounding the hinge part such that it can guide rotation of the support bar within the predetermined angle relative to the body support frame. The hinge part has a first pair of annular leaf springs intervened between the body support frame and a head portion of a rivet serving as a hinge shaft which couples the body support frame to a flat end portion of the support bar, the first pair of annular leaf springs being brought into back-to-back contact with each other; a first flat washer intervened between the body support frame and one of the first pair of annular leaf springs; and second and third flat washers disposed on both side surfaces of the flat end portion of the support bar, respectively.
