Seat belt adjustment release mechanism
A seat belt adjustment release mechanism includes a carrier and a guide piece that is vertically slidable on the carrier. The guide piece includes an aperture configured to receive a seat belt there through and a spring-loaded button anchored on a pivot. The spring-loaded button, when pressed, is rotatable about the pivot between a home position and a depressed position for actuating a seat belt guide release lever.
1. A seat belt adjustment release mechanism comprising:
a seat belt guide having a seat belt guide release lever, the seat belt guide being moveable upon actuation of the seat belt guide release lever;
a carrier; and
a guide piece that is vertically slidable on the carrier, the guide piece including an aperture configured to receive a seat belt there through and a spring-loaded button anchored on a pivot, the spring-loaded button, when pressed, rotatable about the pivot between a home position and a depressed position actuating the seat belt guide release lever, the spring-loaded button having a contact surface engaging the seat belt guide release lever in at least the depressed position, the contact surface being sloped relative to the vertical direction.
2. The mechanism as recited in claim 1 , wherein the spring-loaded button includes a user-interface surface that is sloped relative to the vertical direction.
3. The mechanism as recited in claim 1 , wherein the pivot includes one or more pins.
4. The mechanism as recited in claim 1 , wherein the carrier has vertical rails and the guide piece has sliders mounted on the vertical rails.
5. The mechanism as recited in a claim 1 , wherein the spring-loaded button is vertically above the aperture.
6. The mechanism as recited in claim 1 , wherein the contact surface is sloped at an angle of 45° relative to the vertical direction.
7. The mechanism as recited in claim 1 , wherein the spring-loaded button has a first end attached to the pivot and a second end that is free, and the contact surface is intermediate the first and second ends.
8. The mechanism as recited in claim 1 , wherein the contact surface is on a friction element mechanically secured on the spring-loaded button.
9. The mechanism as recited in claim 1 , wherein the contact surface includes a low-friction material.
10. The mechanism as recited in claim 9 , wherein the spring-loaded button has a first end attached to the pivot and a second end that is free, and the first end is vertically above the second end.
