Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fall prevention device that prevents a vehicle seat belt from falling off a seat.

[0002]

[Prior art]

 Conventionally, seatbelts have been used as an occupant restraint system that protects occupants in the event of a vehicle collision.When used in folding bench seats, etc., the seatbelt must be folded when the backrest is folded. As a device for preventing the seat belt from falling off, as shown in FIG. 3, both ends of a belt 30 formed of a cloth-like member are fixed to the upper rear surface of the seat 2 as shown in FIG. The seat belt 4 having the base end fixed to the vehicle body is inserted between the inner periphery of the central portion of the belt 30 and the seat 2 so that the seat 2 and the backrest 3 are inserted, and the seat belt 4 is inserted by the belt 30. It is known to prevent the passenger from falling out of the seat 2.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional device, the belt for preventing the seat belt from falling off is formed separately from the seat and then fixed to the seat by sewing or the like, which requires labor and increases the manufacturing cost. was there.

Therefore, an object of the present invention is to provide a vehicle seat belt fall-out prevention device capable of reducing manufacturing cost with a simple structure.

[0005]

[Means for Solving the Problems]

 According to the present invention, a seat belt is inserted from the rear of the seat into the gap between the seat and the backrest, and a trim wire for fixing the end portion of the seat skin is arranged along the rear of the seat frame. Is exposed to the outside of the epidermis, and a bent portion is bent in a convex shape, and the seat belt is inserted into the bent portion.

[0006]

[Action]

 Since the seat belt is restricted from moving to the left and right between the inner circumference of the bent part that bends in a convex shape and the outer circumference of the skin of the seat, it is possible to prevent the seat belt from falling off the seat and to the rear of the seat frame. Since the bent portion is provided and exposed in a predetermined section of the arranged trim wire, the backrest can be smoothly folded.

[0007]

【Example】

 1 and 2 show an embodiment of the present invention.

As shown in FIG. 1, the seat 2 is fixed to the interior of a vehicle (not shown), and a backrest 3 is rotatably coupled to the rear of the seat 2 via a hinge (not shown). The backrest 3 is rotatably supported by a lever or the like (not shown) so that the backrest 3 forms a folding bench seat.

The seat 2 is composed of a cushion pad 7 formed of a member having elasticity, and the outer peripheries of the upper surface and the side surface of the cushion pad 7 are covered with a skin 6 formed of a cloth-like member, while The lower surface is fixed to the vehicle body 1 via a seat frame 5 which is arranged in the width direction of the seat 2, that is, in a direction traversing the vehicle body 1.

The seat frame 5 formed of a substantially cylindrical member is arranged on the lower surface of the cushion pad 7 at the rear end of the seat 2 in the figure, and similarly at the front end of the seat 2 not shown. The cushion pad 7 is fixed to the vehicle body 1 via the seat frame 5.

At the rear end of the seat 2, the end of the outer skin 6 is fixed to a trim wire 8 which is formed of a rod-shaped member and is fixed to the seat frame 5 by a fixing means (not shown) such as sewing or gluing. Is fixed to the outer periphery of the seat 2. Although not shown, the front and side ends of the outer skin 6 are also fixed to the seat frame 5 via the trim wires 8 in the same manner as above.

The trim wire 8 is fixed to the seat frame 5 inside the outer skin 6, and as shown in FIG. 2, a recess 21 having a predetermined width and depth is formed in the center of the rear end surface of the seat 2. Therefore, the central portion of the trim wire 8 is exposed to the outside of the seat 2 from the side surface 22 of the recess 21. The central portion of the trim wire 8 exposed from the outer skin 6 is bent upward along the rear end surface of the seat 2 to form a bent portion 9 that is bent in a U shape with its opening facing downward.

The bent portion 9 formed by bending the center portion of the trim wire 8 which is a predetermined section has a width of the inner circumference set to a value wider than the width of the seat belt 4, and the height of the bent portion 9 is The height is set to be almost equal to the upper surface of the seat 2.

As shown in FIG. 1, the bent portion 9 and the skin 6 on the side surface of the seat 2 are in contact with each other, and the base end is located between the bent portion 9 and the skin 6 on the upper surface of the seat 2. The seat belt 4 which is locked to the seat belt 4a is inserted through the other end, and the seat belt 4 is inserted between the seat 2 and the backrest 3 from the rear of the vehicle body 1 toward the front. The widthwise displacement of the vehicle body 1 is restricted by the bent portion 9 provided on the trim wire 8. The width of the buckle 4a is set to a value larger than the width of the inner circumference of the bent portion 9.

With the above-mentioned configuration, the operation will be described.

At a riding position in which the backrest 3 is held at a predetermined angle, a seatbelt 4 that is inserted between the seat 2 and the backrest 3 toward the front of the vehicle body 1 is disposed in the central portion of the seat 2. Since the bending portion 9 of the trim wire 8 and the skin 6 of the seat 2 restrict the displacement of the vehicle body 1 in the upward and downward directions and in the direction crossing the vehicle body 1, the vehicle body 1 may fall off from the seat 2 due to vibration or the like. Instead, since it is always provided on the upper surface of the seat 2, the occupant can easily operate the buckle 4a.

The occupant can restrain his / her body by inserting a seat belt (not shown) arranged on the vehicle body 1 side into the buckle 4a.

Further, even if the seat belt 4 is pulled out from the base end side, that is, from the rear of the seat 2, the buckle 4 a engages with the bent portion 9, so that the seat belt 4 is separated from the seat 2 and the backrest 3. The buckle 4a does not fall out of the space and is always disposed on the upper surface of the seat 2 so that the operation by the occupant can be facilitated.

On the other hand, when the backrest 3 is turned forward to be folded, the seatbelt 4 is also displaced forwards and backwards of the vehicle body 1 as the backrest 3 is turned. Since the up and down or left and right displacement and the displacement in the pulling out direction are regulated by the portion 9, it does not fall off from the upper surface of the seat 2 and the operability when the occupant wears the seat belt 4 can be improved. it can.

In this way, the seat belt 4 was inserted between the inner circumference of the bent portion 9 and the upper surface of the skin 6 of the seat 2 in which the trim wire 8 on the rear portion of the seat 2 was bent with a predetermined width. Therefore, it is not necessary to specially provide a member for preventing the seat belt 4 from falling off on the seat 2, and the bending portion 9 provided on the trim wire 8 which is a constituent member of the seat 2 can prevent the seat belt 4 from falling off. It is possible to promote reduction of manufacturing cost and labor.

In the above embodiment, the bent portion 9 is bent in a "U" shape with the opening facing downward, but it can be formed by a semicircle or the like, although not shown, and The width of the bent portion 9 can also be set according to the number of seat belts 4 to be inserted.

[0022]

[Effect of device]

 As described above, according to the present invention, a predetermined section of the trim wire arranged at the rear of the seat is exposed to the outside and a bent section is formed by bending the exposed section, and the upper surface of the seat skin and the bent section are formed. Since the seat belt is inserted between the seat belt and the seat belt, it is possible to regulate the displacement of the seat belt and it is not necessary to provide a seat member with a member for preventing the seat belt from falling off. The seat belt can be prevented from falling off by a simple structure for forming the seat, and reduction of manufacturing cost and labor can be promoted.
