摘要

#CMT# #/CMT# The lock has a rotary latch bolt (2) for accommodating and locking a locking frame (1) and a detent pawl (3). The bolt moves from a main locking position to an opening position via a prelocking position during an opening process. A toggle spring (4) is connected with the bolt, and exerts force on movement of the bolt during the opening process. Force of the spring acts between the main locking position and the prelocking position and between the prelocking position and the opening position of the bolt in closing direction (9) and opening direction of the bolt, respectively. #CMT#USE : #/CMT# Lock for a door of a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The toggle spring is connected with the latch bolt, and exerts the force on the movement of the latch bolt during the opening process, so that the latch bolt works against acceleration of the latch bolt during separation of the detent pawl to cause deceleration of the latch bolt, thus effectively absorbing and/or suppressing unwanted opening noise caused by the latch bolt. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of opened lock housing with a latch bolt in a main locking position. 1 : Locking frame 2 : Rotary latch bolt 3 : Detent pawl 4 : Toggle spring 9 : Closing direction.
