Abstract

A seat for a vehicle is provided with a sliding device including a slide-lock mechanism, the sliding device sliding a seat body in a case of releasing the slide-lock mechanism, a seatback including a reclining device, the seatback being tilted forward in a case of releasing the reclining device, a seat cushion including a tip-up device, the seat cushion being tipped up in a case of operating the tip-up device and a walk-in mechanism including a lever, the walk-in mechanism configured to release the slide-lock mechanism, release the reclining device and operate the tip-up device in proportion to a shifting length of the lever. The tip-up device is operated in a case where the lever is shifted in an intermediate position and the slide-lock mechanism and the reclining device are released in a case where the lever is shifted in an end position.

Claims

1. A seat for a vehicle comprising:

a sliding device including a slide-lock mechanism, the sliding device configured to slide a seat body upon releasing the slide-lock mechanism;

a seatback including a reclining device, the seatback configured to be tilted forward upon releasing the reclining device;

a seat cushion including a tip-up device, the seat cushion configured to be tipped up upon operating the tip-up device; and

a walk-in mechanism including a lever, the walk-in mechanism configured to release the slide-lock mechanism, release the reclining device, and operate the tip-up device relative to a position of the lever.

2. The seat of claim 1, wherein the walk-in mechanism is configured to operate the tip-up device upon moving the lever to an intermediate position, and to release the slide-lock mechanism and the reclining device upon moving the lever to an end position.

3. The seat of claim 1, wherein the walk-in mechanism comprises:

a slide-release link pivotally supported by the lever; and

a slide-release plate including a slide-release wire connected to the slide-lock mechanism, a reclining-release wire connected to the reclining device and a pin leaving a clearance to the slide-release link,

the lever being connected to the tip-up device to operate the tip-up device upon moving the lever to an intermediate position,

the lever being configured to clear the clearance so that the pin presses the slide-release link whereby the slide-release plate swings and the slide-release wire and the reclining-release wire are pulled so as to release the slide-lock mechanism and the reclining device upon moving the lever to an end position.

4. A seat for a vehicle comprising:

a sliding device including a slide-lock mechanism, the sliding device configured to slide a seat body upon releasing the slide-lock mechanism;

a seatback including a reclining device, the seatback configured to be tilted forward upon releasing the reclining device;

a seat cushion including a tip-up device, the seat cushion configured to be tipped up upon operating the tip-up device; and

a walk-in mechanism including a lever, the walk-in mechanism configured to release the slide-lock mechanism, release the reclining device, and operate the tip-up device relative to a position of the lever, wherein the walk-in mechanism is configured to operate the tip-up device upon moving the lever to an intermediate position, and to release the slide-lock mechanism and the reclining device upon moving the lever to an end position.

5. The seat of claim 4, wherein the walk-in mechanism comprises:

a slide-release link pivotally supported by the lever; and

a slide-release plate including a slide-release wire connected to the slide-lock mechanism, a reclining-release wire connected to the reclining device and a pin leaving a clearance to the slide-release link,

the lever being connected to the tip-up device to operate the tip-up device upon moving the lever to an intermediate position,

the lever being configured to clear the clearance so that the pin presses the slide-release link whereby the slide-release plate swings and the slide-release wire and the reclining-release wire are pulled so as to release the slide-lock mechanism and the reclining device upon moving the lever to an end position.

6. A vehicle seat, comprising:

a sliding device for sliding the vehicle seat, the sliding device including a slide-lock mechanism;

a seat cushion supported above the sliding device and including a tip-up device, the seat cushion configured to be tipped up upon operating the tip-up device;

a seatback supported with respect to the seat cushion and including a reclining device, the seatback tilting forward upon release of the reclining device; and

a walk-in mechanism including a lever, the walk-in mechanism configured to release the slide-lock mechanism and to release the reclining device and operate the tip-up device depending on the position of the lever.

7. The vehicle seat of claim 6, wherein the walk-in mechanism is configured to operate the tip-up device in a case of shifting the lever to a first position, to release the slide-lock mechanism and the reclining device in a case of shifting the lever to an second position.

8. The vehicle seat of claim 6, wherein the walk-in mechanism comprises:

a slide-release link pivotally supported by the lever; and

a slide-release plate including a slide-release connection connected to the slide-lock mechanism, a reclining-release connection connected to the reclining device and a pin leaving a clearance to the slide-release link;

wherein the lever is connected to the tip-up device to operate the tip-up device when the lever is shifted to the first position;

wherein the lever is configured to clear the clearance so that the pin presses the slide-release connection whereby the slide-release plate moves and the slide-release connection and the reclining-release connection are moved to release both the slide-lock mechanism and the reclining device in a case of shifting the lever to the second position.
