Abstract

A conveyance seat includes a lower rail, an upper rail, and a reinforcing member disposed on the lower rails to inhibit deformation of the lower rail. The reinforcing member is disposed in a rear end portion of the lower rail and extended rearwardly from the rear end portion of the lower rail, an upper surface pressing portion of the reinforcing member is disposed forwardly from the rear end portion of the lower rail, and a bent portion of the reinforcing member is disposed rearwardly from the rear end portion of the lower rail and adjacent to a tip portion of the lower rail.

First claim

What is claimed is:

1. A conveyance seat comprising:
a lower rail disposed on a vehicle constituting member;
an upper rail disposed on the side of a seat main body and slidably and movably supported by the lower rail; and
a reinforcing member disposed on the lower rail to inhibit deformation of the lower rail,
wherein the lower rail has a lower surface portion having a flat plate shape substantially parallel to the vehicle constituting member, side surface portions having a flat plate shape and rising from both ends of the lower surface portion, upper surface portions having a flat plate shape and returned inwardly from upper ends of both the side surface portions, and tip portions having a flat plate shape and suspended from inner end portions of both the upper surface portions,
the reinforcing member integrally has a rising portion rising along the side surface portion of the lower rail, an upper surface pressing portion returned inwardly from an upper end of the rising portion to cover the upper surface portion of the lower rail from the upside, and a bent portion suspended from an inner end portion of the upper surface pressing portion, and
the reinforcing member is disposed in a rear end portion of the lower rail and extended rearwardly from the rear end portion of the lower rail, the upper surface pressing portion is disposed forwardly from the rear end portion of the lower rail, and the bent portion is disposed rearwardly from the rear end portion of the lower rail and adjacent to the tip portion of the lower rail.

2. The conveyance seat according to claim 1 , wherein the reinforcing member has a bottom surface portion which is interposed between the lower surface portion and the vehicle constituting member and formed integrally with the rising portion,
the bottom surface portion has a hole portion into which a fixing portion to fix both of the lower rail and the reinforcing member to the vehicle constituting member is inserted, and
the hole portion is formed at a position shifted from the upper surface pressing portion and the bent portion in a longitudinal direction of the lower rail with the reinforcing member being fixed together with the lower rail.

3. The conveyance seat according to claim 1 , wherein the conveyance seat has at least one set of the lower rail and the upper rail, and
the reinforcing member is disposed in one lower rail on a side where a buckle attaching bracket to be attached to a seat belt buckle to be disposed in the seat main body is disposed.

4. The conveyance seat according to claim 3 , wherein the rising portion of the reinforcing member is only disposed in the side surface portion of the lower rail on a side opposite to a side of the other lower rail where the buckle attaching bracket is not disposed, in both the side surface portions of the one lower rail.

5. The conveyance seat according to claim 1 , wherein a length of the bent portion in a suspended direction is smaller than a length of the tip portion in the suspended direction.
