WALK-IN APPARATUS FOR VEHICLE SEAT

摘要

A walk-in apparatus for a vehicle seat includes: a seat rail slidably supporting a vehicle front seat; a slide lock mechanism non-slidably holding a seat cushion of the seat on the seat rail; an operation lever turnably supported by a seatback of the seat; and a link mechanism allowing the seat to be capable of sliding forward by releasing the operation of the slide lock mechanism via a connection unit based on a turning operation of the operation lever. The link mechanism includes a turning link turning based on a pulling force to the connection unit; a lock release link turning based on the turning of the turning link, and thus, releasing the operation of the slide lock mechanism; and a torque absorbing mechanism provided between the turning and lock release links, and limiting a pulling force to the turning link to a predetermined value or less.

1. A walk-in apparatus for a vehicle seat comprising:
a seat rail that slidably supports a vehicle front seat; a slide lock mechanism that non-slidably holds a seat cushion of the vehicle front seat on the seat rail; an operation lever that is turnably supported by a seatback of the vehicle front seat; and a link mechanism that allows the vehicle front seat to be capable of sliding forward by releasing the operation of the slide lock mechanism via a connection unit based on a turning operation of the operation lever, wherein the link mechanism includes
a turning link that turns based on a pulling force applied to the connection unit;a lock release link that turns based on the turning of the turning link, and thus, releases the operation of the slide lock mechanism; anda torque absorbing mechanism that is provided between the turning link and the lock release link, and limits a pulling force, which is applied to the turning link from the connection unit, to a predetermined value or less which is set in advance.
