Abstract

A lace latch with power release, comprising: an integral single motor; a two-stage gear drive system for performing the cinching and power release functions of the latch, wherein rotation of the motor in one direction drives a gear that connects with the cinching/release mechanism of the latch (10) to perform the cinching function of the latch, during the cinching function of the latch pawl of the latch will move about its pivot axis from an initial/secondary latched position to a final/primary latched position, and rotation of the motor in the opposite direction will drive the cinching/release mechanism to fully release the latch by moving the latch pawl of the latch to a fully open position, allowing the pawl to freely rotate to its open position; and a lace control lever that, in use, releases the lace drive link from the latch claw.

Detailed Description

A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of illustration, not limitation.

Referring now to the drawings, a miniature cinching latch 10 having power release capability is disclosed herein.

The latch 10 has a strap control function and a service release for manual operation. The latch 10 is small enough to be used in a variety of vehicle locations (i.e., trunk, hood, small compartment access). The latch 10 has a two-stage latching system with an initial/secondary position (see at least fig. 2A) and a final/primary position (see at least fig. 2B). The cinching function may move the latch from the initial position to the final position against the required load. The lace control system can interrupt the tightening function throughout the lace stroke.

The latch 10 uses an integrated single motor 12 with a two-stage gear drive system 14 to perform the cinching and power release functions. The motor rotates in one direction to drive the

gears

16 and 18, the

gears

16 and 18 are coupled to a tie-down/release mechanism 20 to perform the tie-down function. See at least fig. 1-2B. This will move the latching pawl 22 about its pivot axis from the initial/secondary latching position (fig. 2A) to the final/primary latching position (fig. 2B). Rotation of the motor 12 in the opposite direction will then drive the tie-down/release mechanism 20 to fully release the latch. This function will act to move the latch pawl 24 to the fully open position (see at least fig. 3B), allowing the pawl 22 to rotate freely to its open position.

An additional lever or lace control lever 26 is used to control the lace mechanism 20 acting on the lace drive link 28 and disengage the lace drive link 28 from the latch pawl 22. The manual service device will use the lace lever 26 to release whether the latch 10 is tightened or not.

In addition, the integrated switch 30 will communicate with the body controller 32 to identify the functional position of the selected lever (pawl 24, pawl 22, tie-down/release mechanism 20).

The tether latch 10 is useful for all vehicles. The latch has a tie-down/power release mechanism 20, the tie-down/power release mechanism 20 working with a single motor 12 and a two-stage gear system 14. The latch 10 can be used in all vehicles requiring lift gates, trunks and storage bins.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, element components, and/or groups thereof.

While the disclosure has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the disclosure not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this disclosure, but that the disclosure will include all embodiments falling within the scope of the claims.

Claims
