Japanese Patent No. 5097790

In Patent Document 1, a seat cushion frame, a seat belt buckle, and the like are attached to a slide rail (so-called “upper rail”).
On the other hand, in making such a slide rail device, it is required to reduce the weight.
Usually, in producing a slide rail device, a metal such as an iron plate or an alloy is used to ensure strength.
In order to realize weight reduction in such a state, it is necessary to reduce the thickness of the iron plate or alloy, but it is necessary to avoid a decrease in strength due to this.
Accordingly, there has been a demand for development of a technique capable of reducing the thickness by reducing the thickness of an iron plate, an alloy, or the like, and ensuring the strength capable of sufficiently supporting the entire vehicle seat and the load from the occupant.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle slide rail device capable of realizing weight reduction and ensuring sufficient strength. .

  According to the slide rail device of the first aspect, the subject is a slide rail device that slides a vehicle seat in the vehicle front-rear direction. The slide rail device includes a lower rail that is fixed to a vehicle floor, and a lower rail that is fixed to the lower rail. An upper rail that is slidable in the longitudinal direction of the vehicle. The lower rail includes a lower rail body portion and a lower rail cover portion that covers an outer side of the lower rail body portion. It is solved by the structure.

If it is said attachment structure, a lower rail main-body part can be made into a double structure.
For this reason, when the lower rail cover part is made of a lightweight material, it is possible to reduce the weight while maintaining the same thickness as that of the conventional lower rail member.
Thus, both weight reduction and rigidity maintenance are realizable.

At this time, as described in claim 2, the lower rail main body portion covers the bottom surface portion, the side surface portions standing from the inner and outer end sides of the bottom surface portion, and the bottom surface portion from the upper end of the side surface portion. It is preferable that a space for accommodating the lower side of the upper rail is formed, and the lower rail cover portion is extended to a position covering the flange.
If comprised in this way, the rigidity of a slide rail apparatus will improve.

  At this time, as described in claim 3, a member mounting portion that is indirectly or directly connected to the vehicle seat is formed on the upper side of the upper rail, and the lower rail main body portion is A sliding hole extending in the front-rear direction for projecting the member mounting portion upward is formed, and the lower rail cover portion is formed on the outer side of the lower rail body portion with the sliding hole exposed. It is preferable that it is coated.

  If comprised in this way, since a member attaching part can slide with respect to a lower rail in the state which protruded from the sliding hole, a vehicle seat can be attached reliably and simply.

  At this time, the upper rail is sandwiched between the outer rail member disposed on the vehicle outer side, the inner rail member disposed on the vehicle inner side, the outer rail member and the inner rail member. An outside member attachment portion that is indirectly or directly connected to the vehicle seat is formed on the upper side of the outer rail member. On the upper side of the inner rail member, an inner member mounting portion that is indirectly or directly connected to the vehicle seat is formed, and the fall prevention member includes the outer member mounting portion and the inner member mounting portion. It is preferable to be sandwiched between the two parts.

Thus, when the upper rail is configured by the outer rail member, the inner rail member, and the fall prevention member sandwiched between the outer rail member and the inner rail member, the rigidity against the fall of the upper rail is increased. It is suitable for improving.
In addition, since the fall prevention member is sandwiched between the outer member mounting portion (the upper side of the outer rail member) and the inner member mounting portion (the upper side of the inner rail member), the rigidity of the connecting portion with the vehicle seat is high. Become.
Furthermore, when the fall prevention member is made of a lightweight material, it is possible to reduce the weight while maintaining the same thickness as that of the conventional upper rail.
Thus, both weight reduction and rigidity maintenance are realizable.

  At this time, when the outer member mounting portion, the inner member mounting portion, and the fall-preventing member protrude above the sliding hole, rigidity can be secured and weight reduction can be achieved. This is preferable because of improved properties.

Specifically, as in claim 6, at least one of the lower rail cover member and the fall prevention member is formed of carbon fiber reinforced resin.
Furthermore, at this time, as in claim 7, it is preferable that the carbon fiber reinforced resin is designed so that the carbon fiber direction has a predetermined angle with respect to the applied force when the vehicle seat is used.

Since the carbon fiber reinforced resin is a lightweight and high strength material, use of this material for at least one of the lower rail cover member and the fall prevention member can realize weight reduction and rigidity ensuring.
Further, the durability direction of the carbon fiber reinforced resin varies depending on the traveling direction of the fiber.
That is, the direction in which the force is applied can be optimally reinforced by controlling the fiber running direction of the carbon fiber reinforced resin.
For example, in order to oppose the twist direction, the fiber running direction of the carbon fiber reinforced resin may be controlled to about 45 ° with respect to the additional force.
Thus, by controlling the fiber running direction of the carbon fiber reinforced resin, the rigidity can be controlled to be optimized.

According to the first aspect of the present invention, it is possible to achieve both weight reduction and rigidity maintenance of the lower rail.
According to invention of Claim 2, the rigidity of a slide rail apparatus improves.
According to invention of Claim 3, a vehicle seat can be attached reliably and simply.
According to the invention of claim 4, it is possible to realize both weight reduction and rigidity maintenance of the upper rail.
According to the invention of claim 5, it is possible to achieve rigidity and weight reduction and to improve mounting workability.
According to invention of Claim 6, weight reduction and rigidity ensuring are realizable.
According to invention of Claim 7, it can control to optimize rigidity by controlling the fiber running direction of carbon fiber reinforced resin.
