Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a long slider stopper structure adopted in a one-box car or the like.

[0002]

[Prior art]

 Recently, so-called one-box vehicles, which can be used for various purposes, have been attracting attention. In such one-box vehicles, various measures have been taken to make effective use of the interior of the vehicle.

For example, a long slide rail is extended from the front end to the rear end of the rear side space, and the first and second front and rear rear seats are slidably and lockably supported on the slide rail. It has been proposed that the seat can be set at any position when the rear seat is folded and stored to create a large luggage space, or when the seat is fully flattened or made into a table.

[0004]

[Problems to be solved by the device]

 When a seat with such a structure is used as an original seat, the distance from the front seat and the seat belt mounting position are restricted by vehicle safety standards, etc., and the sliding range that can be used as a seat is limited, and It is not preferable in terms of safety if the seat slides out of the seat use range without knowing it.

In view of the above point, an object of the present invention is to provide a long slider stopper structure capable of reliably preventing the seat from sliding out of the seat use range without the occupant's knowledge.

[0006]

[Means for Solving the Problems]

 Therefore, the long slider stopper structure according to the present invention uses a slide rail seat in an automobile seat in which the seat is slidably supported by a long slide rail extending in the front-rear direction of the vehicle body and can be set at an arbitrary position. A stopper is swingably supported around a vertical axis near the boundary between the range and the outside of the range, and the stopper is swingably biased to the seat slide regulation position, while the stopper at the regulation position is abutted. A lock member that locks the seat is provided so that it can be retracted and urged in the protruding direction, the locked stopper prevents the seat from sliding out of the seat use range, and the lock member is retracted when the lock member is retracted. While the regulation can be released, the lock member is retracted by the swing of the stopper accompanying the sliding of the seat from outside the seat use range to the seat use range. Characterized in that the formation of the urchin guide portion.

The stopper may be biased by, for example, two coil springs in opposite directions so as to be positioned at the restriction position, or may be a leaf spring.

The guide portion may be any one as long as the lock member is retracted by the swing of the stopper accompanying the slide of the seat, and for example, the inclined surface of the lock member may be formed to serve as the guide portion.

[0009]

[Action and effect of the device]

 According to the present invention, since the stopper is biased to the slide restricting position and is locked by the lock member, even if the seat is slid out of the seat use range, the stopper restricts the slide. Therefore, when the seat is operated to slide, the seat does not slide out of the seat use range without the passenger's knowledge, and safety can be guaranteed.

When the seat is slid out of the seat use range, the lock member is retracted to unlock the stopper, so that the slide regulation by the stopper is released and the seat can be slid out of the seat use range.

When the seat slides out of the seat use range, the stopper self-returns to the original restricted position by the biasing force, and the locking member protrudes and is locked on the side opposite to the initial position. When sliding into the use range, the stopper is swung along with the passage of the seat and the lock member is retracted by the guide portion, so that the seat can be freely slid into the use range of the seat.

Further, since the stopper and the lock member are self-returned to the regulated position and the protruding state by the urging force, the stopper and the lock member are not forgotten to return and the reliability is high.
