Walk-in apparatus for vehicle seat

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;
• and
• a 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, and wherein the torque absorbing mechanism includes:
• an intermediate link which is mounted to a transmission shaft in such a way as not to be rotatable relative to the transmission shaft, and
• a biasing member biasing the intermediate link and the turning link.
