Abstract

The latch includes a ratchet and pawl operable to move between an engaged position to hold a striker and a released position to permit the striker from exiting the latch. In addition, a release lever and a lock lever are pivotally mounted to the opposite surface of the latch housing. A lock link lever connects the release lever to the lock lever, having a first end pivotally mounted to the lock lever and a second end slidably located in a slot on the release lever. Actuating the release lever while the second end of the lock link lever is in its locked position pivots the lock link lever in a first arc and actuating the release lever while the lock link lever is in its unlocked position pivots the lock link lever in a second arc to actuate the pawl into its released position.

First claim

What is claimed is:

1. A latch for an automotive door, comprising:
a housing having an inwardly extending sidewall portion;
a ratchet and pawl mounted to the housing, the ratchet operable to move between a ratchet engaged position to hold a striker and a ratchet released position to permit release of the striker, wherein the pawl is operable to move along a travel path between a pawl engaged position wherein the pawl prevents movement of the ratchet to the ratchet released position, and a pawl released position wherein the pawl permits the ratchet to rotate towards the ratchet released position;
a spring biasing the pawl to the engaged position; and
a resilient finger extending out from the pawl and located so as to drag against the inwardly extending sidewall portion of the housing over a majority of the travel path of the pawl between the released position and the engaged position, thereby slowing the pawl.

2. The latch of claim 1 , wherein the pawl further includes a bumper that is located so as to impact against a portion of the housing when the pawl reaches the engaged position.

3. A latch for an automotive door, comprising:
a housing;
a ratchet and pawl mounted to the housing, the ratchet operable to move between a ratchet engaged position to hold a striker and a ratchet released position to permit release of the striker, wherein the pawl is operable to move along a travel path between a pawl engaged position wherein the pawl prevents movement of the ratchet to the ratchet released position, and a pawl released position wherein the pawl permits the ratchet to rotate towards the ratchet released position;
a spring, biasing the pawl to the engaged position; and
a resilient finger extending out from the pawl, wherein the resilient finger drags along a portion of the housing over a majority of the travel path of the pawl between the released position and the engaged position.

4. The latch of claim 3 , wherein the pawl further includes a bumper that is located so as to impact against a portion of the housing when the pawl reaches the engaged position.

5. The latch of claim 1 , wherein the pawl includes a spring locator sized to coaxially mount a spring and bias the pawl to the pawl engaged position.

6. The latch of claim 5 , wherein the spring locator is located on the same side of the pawl as the resilient finger and extends out from the pawl in the same direction as the resilient finger.

7. The latch of claim 2 , wherein the housing includes peripheral sidewalls, the inwardly extending sidewall portion of the housing is located to frictionally engage the resilient finger and extends transverse to one of the peripheral sidewalls, and the portion of the housing located to impact the bumper extends transverse to another one of the peripheral sidewalls.

8. The latch of claim 2 , wherein the portion of the housing located to impact the bumper is disposed between the pawl and the ratchet.

9. The latch of claim 3 , wherein the pawl includes a spring locator sized to coaxially mount a spring and bias the pawl to the pawl engaged position.

10. The latch of claim 9 , wherein the spring locator is located on the same side of the pawl as the resilient finger and extends out from the pawl in the same direction as the resilient finger.

11. The latch of claim 3 , wherein the resilient finger is positioned to drag along an inwardly extending sidewall portion of the housing.

12. The latch of claim 11 , wherein the housing includes peripheral sidewalls, the inwardly extending sidewall portion of the housing extends transverse to one of the peripheral sidewalls, and the portion of the housing located to impact the bumper extends transverse to another one of the peripheral sidewalls.

13. The latch of claim 4 , wherein the portion of the housing located to impact the bumper is disposed between the pawl and the ratchet.

14. The latch of claim 1 , wherein the resilient finger drags against the inwardly extending sidewall portion of the housing over the travel path of the pawl from the released position to the engaged position.

15. The latch of claim 3 , wherein the resilient finger drags along the housing over the travel path of the pawl from the released position to the engaged position.
