## Abstract

An increase in the lateral dimension of a vehicle seat equipped with a tip up lock cancel mechanism is prevented. In a vehicle seat equipped with a tip up mechanism for retaining the seat cushion at least in a tip up position and a tip up lock cancel mechanism for releasing the seat cushion from a retained condition effected by the tip up mechanism in response to a forward tilting movement of the seat back, the tip up lock cancel mechanism includes a cable encasing member having one end fixed to the seat cushion and another end fixed to a back side frame via a fixing part, and a cable slidably received in the cable encasing member and having one end connected to the tip up mechanism and another end connected to a seat base, the fixing part for fixing the cable encasing member to the back side frame being located on an inner side of the back side frame.

## Claims

### Claim 1

A vehicle seat comprising a seat back pivotally attached to a seat base, a seat cushion attached to the seat back in a rotatable manner relative to the seat back between a seating position and a tip up position tilted upward toward the seat back, a tip up mechanism for retaining the seat cushion at least in the tip up position and a tip up lock cancel mechanism for releasing the seat cushion from a retained condition effected by the tip up mechanism in response to a forward tilting movement of the seat back, wherein:
the seat back includes a pair of back side frames extending downward and connected to the seat base; and
the tip up lock cancel mechanism includes a cable encasing member having one end fixed to the seat cushion and another end fixed to one of the back side frames via a fixing part, and a cable slidably received in the cable encasing member and having one end connected to the tip up mechanism and another end connected to the seat base, the fixing part for fixing the cable encasing member to the back side frame being located on an inner side of the back side frame.

### Claim 2 (depends on 1)

The vehicle seat according to claim 1, wherein the seat back further includes a seat back frame formed by connecting an upper member, a pair of side members and a lower member with one another, and the fixing part is located lower than the lower member when the seat back is in the use position.

### Claim 3 (depends on 1)

The vehicle seat according to claim 1, wherein the seat back includes a seat back frame made of pipe material and a reinforcement member extending between the seat back frame and each back side frame, and the fixing part is integrally formed with the reinforce member.

### Claim 4 (depends on 1)

The vehicle seat according to claim 1, wherein the back side frame corresponding to the fixed part is provided on an outer side of the seat base, and the fixing part projects inwardly of the seat in a position laterally corresponding to the seat base, and is configured to restrict a rearward tilting of the seat back by engaging the seat base.

### Claim 5 (depends on 1)

The vehicle seat according to claim 1, wherein the seat cushion includes a pair of cushion side frames pivotally attached to the seat back at respective base ends thereof, the tip up mechanism being attached to an outer side of one of the cushion side frames, and the seat back further includes a support member attached to a fastening seat formed on an outer side of the corresponding back side frame and having a lower free end rotatably supporting the seat cushion, a recess for passing the cable encasing member in a fore and aft direction when the seat back is in the use position being formed in an outer side part of the back side frame located below the fastening seat.

### Claim 6 (depends on 5)

The vehicle seat according to claim 5, wherein the base end of each cushion side frame is positioned between the corresponding support member and the back side frame.

### Claim 7 (depends on 5)

The vehicle seat according to claim 5, further comprising a slide mechanism for permitting the seat base to slide in the fore and aft direction and selectively fixing the seat base at a selected fore and aft position, wherein the slide mechanism includes a slide lock cancel cable for releasing a lock of a slide position of the seat base, and the slide lock cancel cable is passed through the recess.
