Abstract

A recliner apparatus (10) for a vehicle seat (2) having a seat cushion (11) and a seat back (12) includes a first member (15,17) attached to the seat cushion side, a second member (16,18) attached to the seat back side and relatively rotatable to the first member, a return spring (41) for biasing the seat back forward or backward relative to the seat cushion and a clutch mechanism (39,139) provided between the first member and the second member and operated by centrifugal force action concurrent with a rotational operation of the second member for giving rotational resistance to the second member.

Description

technical field [0001] The present invention generally relates to reclining devices for vehicle seats. More particularly, the present invention relates to a reclining device for a vehicle seat for supporting a seat back to a seat cushion so that an angle between the seat back and the seat cushion can be adjusted. Background technique [0002] In general, reclining devices for vehicle seats have the advantage that the seat back can be fastened in any angular position because the seat back is automatically reset by means of a return spring. However, there arises a problem that when the seat back is quickly pulled back, the seat back violently collides with the occupant, which gives the occupant an uncomfortable feeling. [0003] In order to overcome this problem, for example, as described in JPH7(1995)-137564A (Patent Document 1) or JPH9(1997)-252868A (Patent Document 2), various reclining devices for vehicle seats have been proposed in which the seat The return speed of the...
