Clutch mechanism for vehicle seat
A coupling arm presses a first or second arm of a swing member, connected to a frame of a seat back, by an occupant's backrest load caused by a rear-end collision of a vehicle to pivotally move the swing member. The swing member has a first arm receiving a first backrest load via the coupling arm and a second arm receiving a second backrest load, which is larger than the first backrest load, via the coupling arm. A distance between the first arm and a rotation center of the swing member is longer than a distance between the second and the rotation center of the swing member.
