## Abstract

A vehicle seat includes a lower anchorage that serves as an attachment member for a child safety seat; a bracket; and a base frame that is provided on or above a vehicle body. The lower anchorage is fixed to the base frame via the bracket; and the lower anchorage is integrally assembled to the bracket, with contours of the lower anchorage and the bracket being in contact with each other in a front-rear direction.

## Claims

### Claim 1

A vehicle seat comprising:
a lower anchorage that serves as an attachment member for a child safety seat;
a bracket having a circular hole having a longitudinal axis extending in a vehicle seat front-rear direction; and
a base frame that is provided on or above a vehicle body, wherein:
the lower anchorage is fixed to the base frame via the bracket;
the lower anchorage is integrally assembled to the bracket, with contours of the lower anchorage and the bracket being in contact with each other in a front-rear direction; and
a terminal end of the lower anchorage is arranged within the hole of the bracket,
wherein the terminal end projects along the longitudinal axis, and
wherein the lower anchorage is non-moveably fixed to the base frame via the bracket.

### Claim 2 (depends on 1)

The vehicle seat according to claim 1, wherein the lower anchorage is integrally assembled to the bracket in a state where the lower anchorage is in contact with the bracket in the front-rear direction by an insertion connection structure.

### Claim 3 (depends on 2)

The vehicle seat according to claim 2, wherein in the insertion connection structure, the terminal end of the lower anchorage is inserted into the bracket such that the terminal end is restrained from being pulled in a direction opposite to a direction in which the terminal end is inserted into the bracket, and the terminal end is integrally assembled to the bracket in a state where the terminal end is in contact with the bracket in the front-rear direction.

### Claim 4 (depends on 1)

The vehicle seat according to claim 1, wherein the lower anchorage and the bracket comprise different materials.

### Claim 5 (depends on 1)

The vehicle seat according to claim 1, wherein the lower anchorage is a unitary structure.

### Claim 6 (depends on 1)

The vehicle seat according to claim 1, wherein the hole of the bracket has a shape that corresponds to a shape of an outer surface of the terminal end of the lower anchorage.

### Claim 7 (depends on 1)

The vehicle seat according to claim 1, wherein the lower anchorage continuously extends along the front-rear direction from an opening of the hole of the bracket, through which the lower anchorage extends, to the terminal end of the lower anchorage.

### Claim 8 (depends on 1)

The vehicle seat according to claim 1, wherein the bracket comprises a tool engagement socket.

### Claim 9 (depends on 1)

The vehicle seat according to claim 1, further comprising a second bracket having a hole having a longitudinal axis, wherein the lower anchorage is fixed to the base frame via the bracket and the second bracket.

### Claim 10

A vehicle seat comprising:
a lower anchorage that serves as an attachment member for a child safety seat;
a bracket having a circular hole having a longitudinal axis extending in a vehicle seat front-rear direction; and
a base frame that is provided on or above a vehicle body, wherein:
the lower anchorage is fixed to the base frame via the bracket;
the lower anchorage is integrally assembled to the bracket, with contours of the lower anchorage and the bracket being in contact with each other in a front-rear direction; and
a terminal end of the lower anchorage is arranged within the hole of the bracket,
wherein the terminal end projects along the longitudinal axis, and
wherein the lower anchorage comprises at least one flange.

### Claim 11

A vehicle seat comprising:
a lower anchorage that serves as an attachment member for a child safety seat;
a bracket having a hole having a longitudinal axis; and
a base frame that is provided on or above a vehicle body, wherein:
the lower anchorage is fixed to the base frame via the bracket;
the lower anchorage is integrally assembled to the bracket, with contours of the lower anchorage and the bracket being in contact with each other in a front-rear direction; and
a terminal end of the lower anchorage is arranged within the hole of the bracket,
wherein the terminal end projects along the longitudinal axis, and
wherein the hole is a threaded hole, and the terminal end of the lower anchorage is arranged within the threaded hole of the bracket.

### Claim 12

A vehicle seat comprising:
a lower anchorage that serves as an attachment member for a child safety seat;
a bracket; and
a base frame that is provided on or above a vehicle body wherein:
the lower anchorage is fixed to the base frame via the bracket;
the lower anchorage is integrally assembled to the bracket by an insertion connection structure, with contours of the lower anchorage and the bracket being in contact with each other in a front-rear direction;
in the insertion connection structure:
an end portion of the lower anchorage is inserted into the bracket such that the end portion is restrained from being pulled in a direction opposite to a direction in which the end portion is inserted into the bracket;
the end portion is integrally assembled to the bracket in a state where the end portion is in contact with the bracket in the front-rear direction; and
the end portion of the lower anchorage is connected to the bracket with contours of the end portion and the bracket being in contact with each other in the front-rear direction by engagement of threads.

### Claim 13 (depends on 12)

The vehicle seat according to claim 12, wherein:
the lower anchorage comprises a bent wire; and
at least one end of the lower anchorage is fastened to the bracket by engagement of threads and another end of the lower anchorage is inserted into the bracket such that the lower anchorage is integrally assembled to the bracket in a state where the lower anchorage is restrained from rotating around the one end.
