Abstract
A cinching apparatus for a vehicle latch includes a cable lever coupled, by a pin, to a lead nut which is moved along a lead screw by driving power of a single cinching actuator, and the cable lever and a plurality of latches are connected by a plurality of cinching cables so that a difference in cinching stroke between the plurality of latches may be absorbed, and cinching control is possible.
Claims14
A cinching apparatus in combination with a plurality of vehicle latches, wherein the cinching apparatus controls cinching of the plurality of vehicle latches, the cinching apparatus comprising:
- a lead nut movably engaged to a lead screw connected to a cinching actuator by a worm wheel;
- and
- a cable lever, which is pivotally coupled to the lead nut by a pin, and connected to the plurality of vehicle latches by cinching cables,
- wherein a difference in a cinching stroke between the plurality of vehicle latches is absorbed by the cable lever, and the cinching is controlled by the cable lever,
- wherein the cinching cables include first and second cinching cables, and
- wherein the cinching apparatus further includes:
- a housing having a slot formed along a longitudinal direction of the housing in one side surface of the housing;
- the cinching actuator mounted to the housing and including a rotation shaft on which a worm gear is provided;
