ABSTRACT:
A lock unit for use on automobile seats and the like of the type comprising a latch engageable with a stationary striker, and a ratchet engageable with the latch for retaining the striker in a first, confined position in the lock unit. In a second position of the latch, the latch is released from the ratchet, and the striker is freed. The lock unit has a wedge member whose movement is coupled with the movement of the ratchet into and out of engagement with the latch. The wedge member is urged resiliently to engage one side of the striker while the striker is subject to the binding action by the latch on its opposite side. Accordingly, loosening, chattering and rattling of the striker are suppressed. When the ratchet is moved out of engagement with the latch, the wedge member is moved away from the latch and the striker.
