[Industrial applications]

 The present invention relates to a long slider automatic return stroke stopper 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 space, and the first and second rear seats are slidably and lockably supported on the slide rail, and the rear seat is folded. It has been proposed that the seat can be set at an arbitrary position when it is stored in the case to create a large luggage space, or when it is fully flattened or made into a table, and the usefulness is improved.

When such a seat is used as an original seat, the distance from the front seat, the seat belt attachment position, and the like are restricted by vehicle safety standards, etc., so that the seat can be used only in a limited range.

Therefore, conventionally, a stopper is provided on the slide rail to prevent the first and second rear seats from sliding out of the seat use range between the two by a normal sliding operation, and when the vehicle is running, etc. While ensuring safety, it has been proposed to slide the rear seat by removing the stopper when using the first or second rear seat outside the seat use range.

However, in the conventional stroke stopper, the occupant has to manually insert the stopper into the slide rail after returning the rear seat from the outside of the seat use range to the inside, and the operation is complicated.

[0007]

[Problems to be solved by the device]

 In view of such a problem, the present invention provides a long slide automatic return stroke stopper that automatically returns to a state where the stopper can prevent sliding when the seat is returned to the seat use range. It is an issue.

[0008]

[Means for Solving the Problems]

 Therefore, the long slider automatic return stroke stopper according to the present invention is a slide seat for an automobile in which the seat is slidably supported on a long slide rail extending in the longitudinal direction of the vehicle body and can be set at an arbitrary position. A stopper receiver is formed on the rail near the boundary between the seat use range and the outside of the seat, and the seat supports the stopper so that it can be engaged with and disengaged from the stopper receiver and urged in the engaging direction. While restricting the sliding of the seat out of the seat use range, the stopper receiver or the stopper engaged with the stopper receiver is attached to the stopper as the seat slides out of the seat use range to the seat use range. It is characterized in that a guide portion is formed to be detached.

There may be one sheet or a plurality of sheets. In particular, in the case of a plurality of seats, it is more preferable because it is possible to prevent the foot of an occupant from being caught by preventing the seats from sliding out of the seat use range. The stopper may be supported by a slide type or an oscillating type as long as it can be attached to and removed from the stopper receiver. The stopper may have a plate shape, a lever shape, or a pin shape. The shape of the stopper receiver may be a hole or a notch.

[0010]

[Action and effect of the device]

 According to the present invention, when an attempt is made to slide the seat out of the seat use range, the stopper engages with the stopper receiver and the slide is restricted by the urging force. The seat does not slide out of the seat use range without the knowledge of the occupant, which ensures safety.

When the seat is slid out of the seat use range, the stopper may be manually slid or swung against the biasing force so as to be separated from the stopper receiver.

When the seat is returned to the seat use range, the seat may be slid from the outside of the seat use range into the range, and the stopper once engages the stopper receiver with the urging force. Since the guide portion disengages the stopper from the stopper receiver, the seat can be returned to the seat use range from outside the seat use range without being blocked by the stopper.

Therefore, when the seat is tried to slide out of the seat use range, the stopper always fits into the stopper receiver, and when the seat is slid in the opposite direction, the stopper rides over the stopper receiver by the guide portion, so that the operation is performed. Easy and very convenient.
