## Abstract

The seatbelt anchor mounting structure includes a floor panel to which a seat belt anchor is attached, a cross member disposed on a lower side of the floor panel, and a reinforcement disposed on a lower side of the floor panel and fixed to the seat belt anchor together with the floor panel. The reinforcement is fixed to the cross member at a position above an anchor attachment point, which is an attachment point of the seat belt anchor to the floor panel, and is fixed to the cross member at a position below the anchor attachment point.

## Claims

### Claim 1

A seatbelt anchor mounting structure comprising:
a floor panel on which a seatbelt anchor is mounted;
a cross member disposed below the floor panel; and
a reinforcement disposed below the floor panel and fixed to the seatbelt anchor together with the floor panel, wherein the reinforcement is fixed to the cross member at a position above an anchor mounting point that is a mounting point of the seatbelt anchor on the floor panel, and is fixed to the cross member at a position below the anchor mounting point, wherein:
the floor panel includes a first floor surface portion, a floor inclined surface portion rising from a vehicle rear side end portion of the first floor surface portion toward a vehicle rear side and an upper side, and a second floor surface portion extending from an upper end portion of the floor inclined surface portion toward the vehicle rear side, and the seatbelt anchor is mounted on the floor inclined surface portion;
the cross member includes a bottom wall disposed below and on the vehicle rear side of the anchor mounting point, a front wall extending upward from a vehicle front side end portion of the bottom wall, a rear side wall extending upward from a vehicle rear side end portion of the bottom wall, a front flange extending toward a vehicle front side from an upper end portion of the front wall and disposed above and on the vehicle rear side of the anchor mounting point, and a rear flange extending toward the vehicle rear side from an upper end portion of the rear side wall, and the cross member is fixed to the second floor surface portion by the front flange and the rear flange from below;
the reinforcement includes a front wall, an upper wall, and a lower wall vertically facing the upper wall; and
the reinforcement is fixed to the seatbelt anchor together with the floor panel at the front wall, is fixed to the front flange of the cross member at the upper wall, and is fixed to the bottom wall of the cross member at the lower wall.

### Claim 2 (depends on 1)

The seatbelt anchor mounting structure according to claim 1, wherein the lower wall of the reinforcement is provided with a working hole that penetrates the lower wall, and the working hole is closed by a cover.

### Claim 3 (depends on 1)

The seatbelt anchor mounting structure according to claim 1, wherein:
the floor panel and the reinforcement are fixed to the seatbelt anchor using an anchor mounting bolt passing through the anchor mounting point;
the reinforcement further includes a right wall and a left wall; and
the lower wall, the right wall, and the left wall of the reinforcement cover the anchor mounting bolt from below and a vehicle right-left direction.

### Claim 4 (depends on 3)

The seatbelt anchor mounting structure according to claim 3, wherein the reinforcement is fixed to the front flange of the cross member also at the right wall and the left wall.

### Claim 5 (depends on 3)

The seatbelt anchor mounting structure according to claim 3, further comprising a sealing material extending continuously over an entire circumference, wherein the sealing material is disposed between the lower wall, the right wall, and the left wall of the reinforcement, and the floor panel, and is disposed between the lower wall, the right wall, and the left wall of the reinforcement, and the cross member.
