摘要:
A low release effort eccentric double ratchet, double pawl vehicle latch includes a ratchet, a primary pawl, an auxiliary ratchet and a secondary pawl. A drive mechanism including a gear cam wheel sequences movement of the secondary pawl to open and reset the latch. Upon reset, the drive mechanism actuates the auxiliary ratchet back to a closed state in a soft manner without using a hard stop; instead the latch has a cushioning spring that is used to softly stop the gear train during the reset absorbing motor energy and thus eliminating impact noise.
