Vehicle door latch
A vehicle latch assembly includes a plurality of levers for transferring actuation forces to open and close the vehicle latch assembly, at least one of the plurality of levers formed of at least one polymer, wherein the plurality of levers includes a child lock engage lever. Also included is an actuator housing assembly including a water deflector enclosing a connection between an actuator housing and a cover, the vehicle latch assembly reducing sound, reducing release effort, and reducing water intrusion.
1. A vehicle latch assembly comprising:
a plurality of levers for transferring actuation forces to open and close the vehicle latch assembly, at least one of the plurality of levers formed of at least one polymer, wherein the plurality of levers includes a child lock engage lever;
an actuator housing assembly including a water deflector enclosing a connection between an actuator housing and a cover, wherein the water deflector has a pair of side walls that extend over portions of the actuator housing and the cover and the pair of side walls are joined to each other by a portion of the water deflector that forms an exterior of the vehicle latch assembly, the vehicle latch assembly reducing sound, reducing release effort, and reducing water intrusion;
a child security mechanism having a torsion spring connecting the child security mechanism to an inner release mechanism, the torsion spring having a first leg and a second leg;
wherein the first leg of the torsion spring interacts with an inner release lever of the inner release mechanism and the second leg of the torsion spring interacts on a child security actuator lever of the child security mechanism as a cantilever bar with a bump which interacts with the child security mechanism in order to retain it in either a locked or unlocked position; and
a seal foam mounted to an exterior surface of the water deflector.
2. The vehicle latch assembly of claim 1 , wherein at least one of the plurality of levers include at least one reinforcement rib.
3. The vehicle latch assembly of claim 1 , wherein the plurality of levers includes an intermittent lever.
4. The vehicle latch assembly of claim 1 , wherein the plurality of levers includes an outer release lever.
5. The vehicle latch assembly of claim 1 , wherein the plurality of levers includes the inner release lever.
6. The vehicle latch assembly of claim 1 , wherein at least one of the plurality of levers includes a curved interface surface for contacting a bolt, the curved interface surface formed of a polymer.
7. The vehicle latch assembly of claim 1 , wherein the water deflector includes at least one bend.
8. A vehicle latch assembly comprising:
a plurality of levers for transferring actuation forces to open and close the vehicle latch assembly, at least one of the plurality of levers formed of at least one polymer, at least one of the plurality of levers include at least one reinforcement rib;
an actuator housing assembly including a water deflector enclosing a connection between an actuator housing and a cover, wherein the water deflector has a pair of side walls that extend over portions of the actuator housing and the cover and the pair of side walls are joined to each other by a portion of the water deflector that forms an exterior of the vehicle latch assembly;
a seal foam mounted to an exterior surface of the water deflector; and
a child security mechanism having a torsion spring connecting the child security mechanism to an inner release mechanism, the torsion spring having a pair of legs;
wherein, one of the pair of legs of the torsion spring interacts with an inner release lever of the inner release mechanism and the other one of the pair of legs of the torsion spring interacts on a child security actuator lever of the child security mechanism as a cantilever bar with a bump which interacts with the child security mechanism in order to retain it in either a locked or unlocked position.
9. The vehicle latch assembly of claim 8 , wherein the water deflector includes at least one bend.
10. The vehicle latch assembly of claim 8 , wherein the plurality of levers includes at least one of an intermittent lever, an outer release lever, the inner release lever, and a child lock engage lever.
11. The vehicle latch assembly of claim 10 , wherein at least one of the plurality of levers includes a curved interface surface for contacting a bolt, the curved interface surface formed of a polymer.
12. The vehicle latch assembly of claim 1 , wherein the bump is proximate to a distal end of the second leg and the second leg extends from a third leg that extends from the torsion spring.
13. The vehicle latch assembly of claim 12 , wherein the third leg extends in a first direction and the second leg extends in a second direction, the second direction being different from the first direction.
14. The vehicle latch assembly of claim 13 , wherein the first direction is generally orthogonal to the second direction.
15. The vehicle latch assembly of claim 8 , wherein the bump is proximate to a distal end of the other one of the pair of legs of the torsion spring and the other one of the pair of legs of the torsion spring extends from a third leg that extends from the torsion spring.
16. The vehicle latch assembly of claim 12 , wherein the third leg extends in a first direction and the second one of the pair of legs of the torsion spring extends in a second direction, the second direction being different from the first direction.
17. The vehicle latch assembly of claim 13 , wherein the first direction is generally orthogonal to the second direction.
