Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cover for a suspension seat, which is supported by a spring device such as a torsion spring or a coil spring so as to be elastically displaced up and down. .

(Prior Art) In a vehicle such as a truck that is continuously operated for a long time, in order to reduce fatigue of an occupant, the vehicle is suspended by a spring device such as a torsion spring or a coil spring so that it can be elastically displaced vertically. So-called suspension seats are widely used. In the conventional suspension seat, since the suspension device provided between the seat cushion and the floor of the passenger compartment supporting the seat is exposed without being covered, the lower surface of the seat cushion and the floor are not exposed. There have been problems that foreign matter invades in between, impairing the elastic support effect and impairing the appearance of the vehicle interior.

(Problems to be Solved by the Invention) An object of the present invention is to provide an inexpensive and lightweight cover for a suspension seat that can solve all the above-mentioned problems in the conventional suspension seat.

(Means for Solving the Problems) The present invention was devised to achieve the above-mentioned object, and is an upper and lower body provided between a seat cushion of a suspension seat and a body member such as a floor supporting the seat. A cover that is expandable and contractible in a direction is composed of an extruded plate of a flexible resin material in which elongated flat portions extending in the lateral direction and bellows-shaped bellows portions are alternately provided, and The present invention proposes a suspension seat cover characterized in that the V-shaped notch portion formed in a straight line is provided with a bent corner portion extending in the vertical direction.

(Operation) By disposing the cover between the seat cushion of the suspension seat and the body member such as the floor according to the present invention, the outside of the suspension device provided below the seat cushion is covered. Foreign matter is prevented from entering and the appearance inside the vehicle is improved. The cover is composed of an extruded plate of a flexible resin material in which slender flat portions extending in the lateral direction and fold-shaped bellows portions are alternately provided, and the folds are formed at the lower corners of the seat cushion. The V-shaped notch formed in a straight line on the bellows forms the corners that are bent and extend in the vertical direction. Therefore, the structure is extremely simple, lightweight, and inexpensive.

(Embodiment) An embodiment of the present invention will be specifically described below with reference to the accompanying drawings. In the figure, reference numeral 10 is a seat cushion 12 and a seat back 14.
The seat 10 is generally shown, and the seat 10 is supported on the passenger compartment floor 16 by a suspension device (not shown) known per se so as to be elastically displaceable in the vertical direction. The outer peripheral portion of the lower edge of the seat cushion 12 and the passenger compartment floor
An expandable cover 18 is arranged between the cover 16 and the cover 16. In the illustrated embodiment, the cover 18 has a U shape as a whole, and its upper end edges are formed on the left and right side edges 12a and the front edge 12b of the seat cushion 12, respectively. It is fixed by screws, bolts or other suitable fixing means.

The cover 18 is composed of an extruded plate of a flexible resin material such as a flexible vinyl chloride or rubber in which a slender flat surface portion 18a extending in the lateral direction and a bellows-shaped bellows portion 18b are alternately arranged. There is. Each of the fold-shaped bellows portions 18b is formed with a cutout portion 20 that forms a line along the vertical line OO, and the cutout portion 20 has a planar shape (with respect to a horizontal plane) as shown in FIG. V whose projected shape has a vertical angle of approximately 90 degrees
It has a letter shape, and thus the front shape is a main body rhombus as shown in FIG. In order to prevent the cracks from developing from the apexes of the notch portion 20 and growing, a small circular portion is provided at each apex portion as shown in FIG.
22 are formed.

The notches 20 are formed in the folds 18 along two substantially parallel vertical lines OO of the cover material made of an extruded plate that has been cut to a predetermined size, and thus is shown in FIG. As shown by the alternate long and short dash line, by bending the cover material portion outside the line OO, the corner portion 24 that is located below the corner portion 12c of the seat cushion 12 and extends in the vertical direction is formed.
The cover that is formed and has a U-shaped planar shape as a whole
18 is formed. After being bent as described above, the edge of the notch 20 (shown by reference numeral 26 in FIG. 3) may be integrally bonded with an appropriate adhesive, but it is not always necessary to bond it. Instead, you may leave it as it is. The upper edge of the cover 18 is a lower side surface (or lower side surface) of the seat cushion with a screw, a bolt, or an adhesive.
Also, the lower end edge is fixed to the floor 16 by screws, bolts, adhesives or the like.

According to the above configuration, since the suspension device disposed below the seat cushion 12 is covered with the cover 18 that can freely expand and contract in the vertical direction, the foreign matter enters the suspension device and adversely affects the elastic support action. It is possible to further improve the appearance of the vehicle interior without giving Further, since the cover 18 is manufactured by forming a cutout portion 20 by subjecting the cover 18 to a flexible resin material extruded plate as a raw material, there is an advantage that it is extremely inexpensive and lightweight. Further, by providing the cover 18, there is an advantage that dust can be prevented from entering the suspension device to some extent, smooth operation of the sliding portion can be ensured, and premature wear can be prevented.

It should be noted that in the above embodiment, the cover 18 is the seat cushion 12
Although the U-shape is formed so as to cover the left and right side edges and the lower side of the front edge, it is preferable to form the cover 18 in an L shape so that foreign matter can easily enter and a cover is provided from the viewpoint of appearance. The cover 18 may be arranged so as to cover the surface, and the cover 18 may be formed in a substantially rectangular shape so as to cover the four circumferences below the seat cushion 12. Further, the apex angle of the V-shaped notch 20 is basically 90 degrees as shown in the drawing, but especially when the edge 26 is adhered, the apex angle may be made smaller than 90 degrees as necessary to make the edge 26 Can be slightly overlapped, and the edge 26
The vertical angle can be 90 degrees or more when not bonded.

(Effect of the Invention) As described above, the suspension seat cover according to the present invention is vertically expandable and contractible disposed between the seat cushion of the suspension seat and the vehicle body member supporting the seat such as the floor. The cover is formed of an extruded plate of a flexible resin material in which slender flat portions extending in the lateral direction and fold-shaped bellows portions are alternately provided, and the fold-shaped bellows portions are formed in line. The V-shaped cutout portion is provided with a vertically extending corner portion formed by bending, so that foreign matter can be prevented from entering the suspension device below the seat cushion. Since it is possible to provide a cover that has a simple structure, can be improved in appearance, is lightweight, and is inexpensive, it is extremely useful in practice.
