Abstract

A lock release lever attachment structure includes: a case that includes a case body, an upper portion of which opens as a first opening, and a first flange, a slit being formed to penetrate through at least a portion of the first flange in a seat up-down direction along a peripheral edge of the first opening; an operation lever that releases a locked state of a seatback; and a cover that includes a cover body, an upper portion of which opens as a second opening, and a second flange, the first and second openings being placed in communication by inserting the cover body into the case body through the first opening and fixing the cover body inside the case body, and an edge of a covering material that covers a surface of the seatback being inserted into the slit and gripped by the first and the second flanges.

First claim

What is claimed is:

1 . A lock release lever attachment structure comprising:
a case that includes a substantially box-shaped case body, an upper portion of which opens as a first opening, and a first flange formed extending outward from the first opening, a slit being formed so as to penetrate through at least a portion of the first flange in a seat up-down direction along a peripheral edge of the first opening, and the case being attached to a bracket provided to a seatback frame such that the first opening is open in a seat upward direction; an operation lever that is axially supported so as to be capable of swinging between a pair of sidewalls of the case body and that releases a locked state of a seatback by being swing-operated; and a cover that includes a substantially box-shaped cover body, an upper portion of which opens as a second opening and that restricts a swing range of the operation lever, and a second flange formed extending outward from a peripheral edge of the second opening, the first opening and the second opening being placed in communication with each other by inserting the cover body into the case body through the first opening and fixing the cover body inside the case body, and an edge of a covering material that covers a surface of the seatback being inserted into the slit and gripped by the first flange and the second flange.

2 . The lock release lever attachment structure of claim 1 , wherein the slit is formed in the first flange at both end sides of a swing shaft of the operation lever.

3 . The lock release lever attachment structure of claim 1 , wherein a width of the first flange is wider than a width of the second flange at a portion of the second flange overlapping the first flange.

4 . The lock release lever attachment structure of claim 1 , wherein a side plate is formed extending downward from the second flange so as to be insertable into the slit in a state in which the cover overlaps the case and is mounted to the case.

5 . The lock release lever attachment structure of claim 4 , wherein a rib is formed to a sidewall of the case below the slit so as to project outward from an outside face of the sidewall and to extend in the seat up-down direction.

6 . The lock release lever attachment structure of claim 4 , wherein a stopper is formed to a sidewall of the case below the slit so as to project outward from an outside face of the sidewall and abut a front edge or a rear edge of the side plate to restrict swinging of the cover.
