Abstract

A latch is provided. The latch having: a housing; an intermittent lever pivotally mounted to the housing for movement between a latched position and an unlatched position; and an elastomeric feature configured to contact the intermittent lever when it is in the latched position.

Claims (14)

1. A vehicle door latch, comprising:

a housing, wherein the housing has a strengthening feature that increases a thickness of a portion of a wall of the housing such that the portion of the wall of the housing has a thickness greater than the rest of the wall, wherein the strengthening feature is a plurality of ribs that extend from an exterior surface of the wall;

an intermittent lever pivotally mounted to the housing for movement between a latched position and an unlatched position, wherein the intermittent lever is operatively coupled to a pawl of the latch, and wherein movement of the intermittent lever between the latched position and the unlatched position causes a corresponding movement of the pawl between an engaged position and a disengaged position and the pawl is configured to cooperate with a claw of the latch such that movement of the claw into the engaged position prevents the claw from moving from a latched position to an unlatched position;

an elastomeric feature configured to contact the intermittent lever when it is in the latched position, wherein the elastomeric feature is integrally formed with a bumper located in the housing and the bumper has another integral portion located in a throat of the housing;

wherein the pawl is pivotally mounted to the housing for rotation about an axis offset from an axis of rotation of the intermittent lever; and

an elastomeric bumper positioned against an inside surface of the wall of the housing that the ribs extend from and wherein the elastomeric bumper is configured to receive an impact force from a fork bolt of the latch when the it reaches a fully latched position.

2. The latch as in claim 1 , wherein the bumper has a leg portion extending therefrom that terminates at a distal end, wherein the distal end provides the elastomeric feature.

3. The latch as in claim 2 , wherein the bumper has another leg that extends from the bumper in a different direction than the leg portion.

4. The latch as in claim 1 , wherein the plurality of ribs are integrally molded into the housing and the housing is formed from plastic.

5. The latch as in claim 4 , wherein the bumper as a leg portion extending therefrom that terminates at a distal end, wherein the distal end provides the elastomeric feature.

6. The latch as in claim 5 , wherein the bumper has another leg that extends from the bumper in a different direction than the leg portion.

7. The latch as in claim 1 , wherein the elastomeric feature does not contact the intermittent lever when the intermittent lever is in an unlatched position.

8. The latch as in claim 7 , wherein the bumper has a leg portion extending therefrom that terminates at a distal end, wherein the distal end provides the elastomeric feature.

9. The latch as in claim 8 , wherein the bumper has another leg that extends from the bumper in a different direction than the leg portion.
