Abstract

A latching system includes a first lever connected to a first cable having a first cable end, a second lever connected to a second cable having a second cable end, a latch connected to a third cable having a third cable end, and a cable splitter assembly. The cable splitter assembly has a housing with a first end and a second end and a body with an interior surface defining an interior chamber. A carriage is configured to translate within the interior chamber. The carriage includes a carriage body with a plurality of cavities arranged to seat the respective first, second, and third cable ends and a plurality of resilient arms integrally formed as one piece with the carriage body.

First claim

What is claimed is:

1. A latching system comprising:
a first lever connected to a first cable having a first cable end;
a second lever connected to a second cable having a second cable end;
a latch connected to a third cable having a third cable end; and
a cable splitter assembly, the assembly including
a housing having a first end and a second end and a body with an interior surface defining an interior chamber;
a carriage configured to translate within the interior chamber, the carriage having a carriage body with a plurality of cavities arranged to seat the respective first, second, and third cable ends and a plurality of resilient arms integrally formed as one piece with the carriage body.

2. The latching system of claim 1 , wherein the carriage body includes a first side and an opposing second side, and wherein the plurality of resilient arms are integrally formed as part of the first side.

3. The latching system of claim 2 , wherein each resilient arm of the plurality of resilient arms includes a contact surface disposed between the respective resilient arm and the interior surface.

4. The latching system of claim 2 , wherein each resilient arm of the plurality of resilient arms includes a contact member extending away from the first side.

5. The latching system of claim 1 , wherein the carriage further includes a first end and an opposing second end, wherein the carriage body further includes a plurality of channels, each channel in communication with one cavity of the plurality of cavities.

6. The latching system of claim 5 , wherein each cavity is formed at one of the first end or the second end, and wherein an associated channel extends from the other of the first end or second end to the cavity.

7. The latching system of claim 1 , further including
a first terminal at the first cable end;
a second terminal at the second cable end; and
a third terminal at the third cable end,
wherein each of the first, second, and third terminals is configured to sit within a respective cavity of the plurality of cavities and includes a vibration-reducing component.

8. The latching system of claim 7 , wherein each vibration-reducing component is in the form of a ring positioned at least partially around a portion of each respective terminal.

9. The latching system of claim 8 , wherein each ring is formed of an elastomeric material.

10. A cable splitter subassembly comprising:
a housing having a first end and a second end and a body with an interior surface defining a bounded interior chamber;
a carriage configured to translate within the bounded interior chamber, the carriage having a carriage body with a plurality of cavities, each cavity arranged to seat a cable terminal end and opening to a first end of the carriage body or a second end of the carriage body opposite the first end, and a plurality of resilient arms extending from the carriage body, each arm including a contact surface configured to contact a portion of the interior chamber during translation of the carriage within the housing;
a first cable extending through the first end of the housing and the first end of the carriage body, wherein the first cable is connected to a first cable terminal end configured to be seated in a respective one of the pluralities of cavities having an opening in the second end of the carriage body through which the first cable terminal is movable during operation of the cable splitter subassembly; and
a second cable extending through the first end of the housing and the first end of the carriage body, wherein the second cable is connected to a second cable terminal end configured to be seated in a respective one of the plurality of cavities having an opening in the second end of the carriage body through which the second cable terminal end is movable during operation of the cable splitter subassembly opening.

11. The cable splitter subassembly of claim 10 , wherein the second end of the housing includes an opening, the subassembly further including a cap configured to cover the opening, wherein the cap includes a plurality of cap channels extending therethrough such that in an assembled state of the cap with the housing the bounded interior chamber is in communication with an environment external to the housing.

12. The cable splitter subassembly of claim 11 , wherein the carriage body further includes a plurality of channels, each channel in communication with a cavity of the plurality of cavities.

13. The cable splitter subassembly of claim 10 , wherein each contact surface is a portion of a contact member formed at the end of each arm.

14. A cable splitter subassembly comprising:
a housing having a first end and a second end and a body with an interior surface defining a bounded interior chamber;
a carriage configured to translate within the bounded interior chamber, the carriage having a plurality of cavities, each cavity arranged to seat a cable terminal end, and a plurality of resilient arms extending from the carriage, each arm including a contact surface configured to contact a portion of the interior chamber during translation of the carriage within the housing;
a first cable extending through the first end of the housing and a first end of the carriage, wherein the first cable is connected to a first cable terminal end configured to be seated in a respective one of the plurality of cavities;
a second cable extending through the second end of the housing and a second end of the carriage opposite the first end of the carriage, wherein the second cable is connected to a second cable terminal end configured to be seated in a respective one of the plurality of cavities that opens to the first end of the carriage; and
a third cable extending through the second end of the housing and the second end of the carriage, wherein the third cable is connected to a third cable terminal end configured to be seated in a respective one of the plurality of cavities that opens to the first end of the carriage,
wherein the carriage is configured such that pulling the first cable to move the carriage toward the first end of the housing moves the second and third cable terminal ends toward the first end of the housing, pulling the second cable to move the carriage toward the second end of the housing moves the first cable terminal end toward the second end of the housing while the third terminal cable end remains stationary, and pulling the third cable to move the carriage toward the second end of the housing moves the first cable terminal end toward the second end of the housing while the second terminal cable end remains stationary.

15. The carriage splitting assembly of claim 14 , wherein each contact surface is formed by a contact member extending away from carriage body.
