Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a simple foldable vehicle seat that is installed on the side or rear of the driver's seat of a freight vehicle such as a truck.

[Conventional technology]

Conventionally, as shown in FIG. 10, this type of seat has a seat cushion 2 rotatably attached to a leg 1 fixed to the body of a vehicle, and a cushion frame 2A of the seat cushion.
It is known that a seat back 3 is rotatably attached via a bracket 2B. A long hole 2C for rotation is formed in the cushion frame 2A.

[Problem to be solved]

In the simple seat shown in FIG. 10, when the seat cushion 2 is lifted and stored, the operator's clothes or the like may get caught in the elongated hole 2C of the cushion frame 2A, which may impede rotation of the seat cushion. The long hole 2C made the inside visible, spoiling the appearance.

Therefore, this idea makes it possible to close the elongated hole while maintaining the pull-out operation of the cushion frame. This prevents the operator's clothes from getting caught when the seat cushion rotates, resulting in a good appearance. The purpose of the present invention is to provide a simple seat for a vehicle.

[Means for solving problems]

In order to achieve the above-mentioned purpose, this invention attaches the seat cushion rotatably to the legs fixed to the vehicle body, and attaches the seat cushion rotatably to the cushion frame of the seat cushion via a bracket. A simple foldable vehicle seat with a seat back attached thereto, wherein an arcuate guide rail is provided on the legs, a roller that rolls along the guide rail is provided at the rear end of the cushion frame, and the cushion A long hole is opened in the rear side of the frame, and a bush having guide portions extending outward from both edges along the longitudinal direction of the long hole is fitted into the long hole. A cover slider having a size sufficient to cover the elongated hole and having a stopper at its tip that abuts the end of the guide portion,
A pin is slidably clamped or fitted into the guide portion of the bushing fixed to the cushion frame, rotatably inserted through the long holes of the bush and the cushion frame, and rotatably passes through the cover slider. Attached to the leg body, when the seat cushion rotates for storage or seating, the cushion frame and cover slider rotate integrally around the pin, and when the seat cushion is pulled out or stored when sitting, When retracting, the guide section is configured to move back and forth along the cover slider.

[Effect]

In this invention, when lifting the seat cushion upward or lowering the folded seat to the seating position, the elongated hole in the cushion frame is covered by a cover slider that is slidably held in the guide section of the cushion. to prevent clothes, etc., from getting caught in the long holes.

〔Example〕

Preferred embodiments of this invention will be described below with reference to the drawings.

A cushion frame 2A is rotatably attached to a leg 1 fixed to a vehicle body. A long hole 2C is formed in the cushion frame 2A,
A roller 4 is attached to the rear end of the cushion frame 2A. A pin 5 attached to the leg body 1 is rotatably inserted through the long hole of the cushion frame 2A. A cover slider 6 of sufficient size to cover the elongated hole 2C is attached to this pin 5. Note that the bush 7 is fitted into the elongated hole 2C before the pin 5 is inserted. The pin 5 will be inserted into this bush 7. Furthermore, there are two cushion frames 2A, and a cover slider 6 is also attached to the outside of the other elongated hole 2C. Note that a stopper 6A is formed at the tip of the cover slider 6 so as to come into contact with the ends of the guide portions 7A and 7B. The presence of this stopper 6A serves to prevent the cover slider 6 from sliding any further when the pin 5 is located at the lower end of the elongated hole, that is, at the rear end.

The bush 7 is formed with guide portions 7A and 7B extending outward on both longitudinal sides of the elongated hole 2C.
A cover slider 6 is slidably held between A and 7B (see FIG. 2). Note that the tip of the pin 5 is screwed into a nut 8 fixed to the leg body 1.

A seat cushion 2 is attached to the cushion frame 2A, and a seat bag 3 is rotatably attached to the two cushion frames 2A extending rearward of the seat cushion 2 via a bracket 2B. (See Figure 3). This simple sheet is
A recess is formed in the side wall of the vehicle body so that it can be stored in this recess. Seat cushion 2
As shown in FIG. 4, a recess 21 is formed on the back side of the seat cushion 2, which is convenient for lifting the seat cushion 2. A roller 4 provided at the rear end of the cushion frame 2A rolls within a guide rail 9 attached to the leg 1. When the seat cushion 2 is lifted up and erected, the guide portion 7A of the bush 7 fitted into the cushion frame 2A is moved by the weight of the seat cushion 2 or by the user pushing down the seat cushion 2. 7B descends while sliding downward along the cover slider 6 which is stationary in the vertical direction of the leg body 1. Therefore, the seat cushion 2 descends, and as shown in FIG. 6, the descending movement is blocked when the upper end of the elongated hole 2C is engaged with the pin 5. In addition, in FIG. 6, the cover slider 6 rotates in the same direction as the seat cushion 2 rotates, but its position moves upward relative to the elongated hole 2C. On the other hand, when the seat cushion 2 is pulled down to the seated state, the guide portions 7A and 7B move along the cover slider 6.
moves while sliding, and the lower end of the elongated hole 2C is located on the pin 5, that is, the rear end as shown in FIG.
When the left ends of A and 7B collide with the stopper 6A, they are locked. Long hole 2C for pin 5
With the movement of the cover slider 6, the position of the cover slider 6 is displaced along with the pin 5 in the longitudinal direction of the elongated hole 2C. Even if it is locked to the stopper 6, the long hole 2 of the cushion frame 2A
The outside of C is always covered with a cover slider 6. In other words, the cover slider 6 has the elongated hole 2
It is longer than C, so that even if the cushion frame 2A moves back and forth, it can always cover the long hole 2C.

As shown in FIG. 7, the pin 5 is attached in detail by fitting a nylon bushing 7 into the long hole 2C of the cushion frame 2A, and inserting a cover slider 6 between the guide parts 7A and 7B of this bushing. is slidably positioned. The pin 5 is inserted into the opening of the bush 7 and rotatably inserted into the hole of the cover slider 6, and is attached by screwing the threaded portion 5A of the pin 5 into the nut 8 fixed to the leg 1. be. Note that this pin 5 is constituted by a stepped bolt. The reason why nylon is used for the bush 7 is to make the guide parts 7A and 7B easy to slide against the cover slider 6 into which the pin 5 is inserted, and to make it structurally strong. Various other plastic materials can also be used. It is.

The cover slider 6 shown in FIG. 8 is a modified example and is designed to fit into guide portions 7A and 7B as shown in FIG. 9.

〔effect〕

As explained above, according to this invention, an elongated hole is drilled in the cushion frame which extends rearward of the seat cushion and is rotatably attached to the leg body fixed to the vehicle body. A pin attached to the body is inserted, and a cover slider large enough to always cover the long hole is attached to this pin, so in other words, the long hole can be covered at all times while the cushion frame is slidable. Since a cover slider is attached, the cover slider always closes the long hole even when the cushion frame is in the seated position and even in the middle of seating, so the operator's clothes will not get caught. This prevents the rotation of the seat cushion from interfering with the rotation of the seat cushion, and provides a good appearance.
