Abstract

A vehicle seat slide device includes: a lower rail including a base portion fixed to a vehicle body and wall portions connected to ends of the base portion in a width direction; an upper rail supporting a seat and supported by the lower rail to be capable of sliding in an extending direction; and a foreign object blocking member disposed inside the lower rail and attached to the base portion, wherein first and second through holes are provided in positions at which the foreign object blocking member is attached in the base portion, the foreign object blocking member includes an attaching portion and a protruding portion protruding downward from an outside end portion, and the foreign object blocking member is elastically deformed such that the outside end portion is displaced downward.

First claim

What is claimed is:

1. A vehicle seat slide device of a vehicle, comprising:
a lower rail which includes a base portion which is fixed to a vehicle body and a pair of wall portions which are connected to both ends of the base portion in a width direction of the vehicle seat slide device;
an upper rail which supports a seat and is supported by the lower rail in a state of sliding in an extending direction of the lower rail; and
a foreign object blocking member which is disposed inside the lower rail and is attached to the base portion,
wherein a first through hole and a second through hole which is disposed closer to an outside in the extending direction than the first through hole are provided in positions at which the foreign object blocking member is attached in the base portion of the lower rail,
wherein the foreign object blocking member includes an attaching portion which is disposed to pass through the first through hole and to be lower than the base portion, and a protruding portion, which protrudes downward from an outside end portion of the foreign object blocking member, passes through the second through hole of the base portion, and a claw portion provided on a tip of the protruding portion is pressed against a bottom surface of the base portion, and
wherein the foreign object blocking member is elastically deformed such that the outside end portion is displaced downward in a state in which the foreign object blocking member is attached to the lower rail.

2. The vehicle seat slide device according to claim 1 ,
wherein a protrusion which protrudes downward is provided between the attaching portion and the outside end portion in the foreign object blocking member, and
wherein a tip of the protrusion is positioned higher than the tip of the protruding portion and abuts against the base portion of the lower rail.

3. The vehicle seat slide device according to claim 2 ,
wherein a fragile portion which has a lower rigidity than other parts is provided between the protrusion and the outside end portion in the foreign object blocking member.

4. The vehicle seat slide device according to claim 1 ,
wherein the protruding portion includes an outside protruding portion which the claw portion is pressed against on a part closer to the outside in the extending direction than the second through hole in the bottom surface of the base portion of the lower rail, and
wherein a displacement restriction portion which has a higher rigidity than the outside protruding portion and abuts against a part of an inside in the extending direction in acircumferential surface which surrounds the second through hole is provided on the outside end portion of the foreign object blocking member.

5. The vehicle seat slide device according to claim 4 ,
wherein the protruding portion includes
a first lateral protruding portion against which the claw portion is pressed at a part closer to one side in the width direction than the second through hole in the bottom surface of the base portion of the lower rail, and
a second lateral protruding portion against which the claw portion is pressed at a part closer to another side in the width direction than the second through hole in the bottom surface.

6. The vehicle seat slide device according to claim 1 ,
wherein the protruding portion includes
a first lateral protruding portion against which the claw portion is pressed at a part closer to one side in the width direction than the second through hole in the bottom surface of the base portion of the lower rail, and
a second lateral protruding portion against which the claw portion is pressed at a part closer to another side in the width direction than the second through hole in the bottom surface, and

wherein a length of the outside end portion in the width direction is greater than the length in the width direction of other portions in the foreign object blocking member.

7. The vehicle seat slide device according to claim 5 ,
wherein inclined surfaces which incline to be positioned further outside in the width direction the closer to the bottom are provided on both sides of the outside end portion in the width direction.
