Description

[Detailed Description of the Invention] The present invention relates to a piping and wiring structure for a seat, and more specifically, a seat back is rotatably hinged to a seat cushion, and a member housed within the seat back; The present invention relates to a piping and wiring structure for a seat that communicates components housed in the seat cushion with communication members such as tubes and cords.

Generally, in a vehicle seat, etc., as shown in FIG.
An air pump, for example, and various air support mats, as a member 4 housed in the seat cushion 2, are connected by an air tube or the like as a connecting member 5.

However, conventionally, no consideration has been given to troubles of the connecting member 5 caused by tensile or compressive loads due to bending, etc. applied to the connecting member 5, and therefore, when reclining the seat bag 1 or during durability tests, the tubes, cords, etc. There is a risk that the communication member 5 such as the like may be damaged or damaged, and there is a problem that it will not be able to perform its intended function. Further, when the seat back 1 is tilted backward, the connecting member 5 becomes loose, and there is a risk that the feet of the person seated in the rear seat may get caught in the loosened connecting member 5.

The purpose of this invention is to reduce troubles such as breakage and damage to connecting members such as tubes and cords, and to prevent the connecting members from loosening when the seatback is tilted backwards, so that the feet of rear seat occupants will not get caught. The purpose of this invention is to provide a piping and wiring structure for a seat that is safe, has excellent safety, and can improve its appearance, and will be described in detail below with reference to the drawings.

FIG. 2 schematically shows an embodiment of the piping and wiring structure of a seat according to the present invention, in which a seat back 1 is rotatably hinged to a seat cushion 2. The seat back 1 can be freely adjusted in rotation angle by a reclining mechanism (not shown) provided on one side. A hinge bracket 7 is fixed to the seat cushion frame 6, a hinge arm 9 of a seat bag frame 8 is disposed on one side of the bracket 7, and the hinge bracket 7 and the hinge arm 9 are connected to each other by the hinge bolt 1.
0, and is rotatably hinged.

Note that the seat cushion frame 6 is not provided with the hinge bracket 7 on the seat cushion frame 6.
It may be hinged directly to the

A hinge cover 11 made of synthetic resin or the like is attached to the hinge arm 9 as shown in FIG. Inward flange portion 11 formed along the outer peripheral edge of the back side of this hinge cover 11
The hinge cover 11 is attached to the hinge arm 9 in a fitted state by a. This hinge cover 1
An insertion hole 12 for a hinge bolt 10 is bored in the lower part of the hinge bolt 1 . A guide portion 13 of the communication member 5 is formed inside the hinge cover 11 along the longitudinal direction of the hinge cover 11. Further, an insertion hole 14 for the communication member 5 is formed at the lower end of the hinge cover 11, and an insertion hole 15 is formed in the seat cushion frame 6 as well.

A member 3 housed in the seat bag 1;
A communication member 5 such as a tube or a cord that communicates with the member 4 housed in the seat cushion 2 is guided from the side of the seat bag 1 to the upper end of the hinge cover 11, and is guided to the guide portion 13 inside the hinge cover 11. It is guided to the outside of the hinge cover 11 through the insertion hole 14 and then into the inside of the seat cushion 2 through the insertion hole 15 of the seat cushion frame 6.

Different embodiments of the present invention are shown in FIGS. 4 and 5, and the same reference numerals are given to the parts corresponding to those of the above-mentioned embodiment, and further detailed explanation thereof will be omitted. The hinge cover 11 is composed of an upper hinge cover part 21 and a lower hinge cover part 22 which is pivotally supported at the lower end of the upper hinge cover part 21 by a pivot pin 23. is covered and similarly rotates in accordance with the rotation of this hinge arm 9,
The lower hinge cover part 22 is guided through the insertion hole 14 at the lower end of the hinge cover 11 in the embodiment described above, and is guided through the insertion hole 14 in the seat cushion frame 6.
It has the same structure as the above-mentioned embodiment, except that it is configured to cover the communication member 5 led to the hinge arm 5 and is not affected by the rotation of the hinge arm 9. It is.

The above is the configuration of one embodiment of the piping and wiring structure of the seat according to the present invention. According to this configuration, the members accommodated in the seat bag and the members accommodated in the seat cushion The communication member that communicates with the hinge arm is inserted inside the hinge cover that covers the hinge arm, so there is no risk of it being hit by luggage stored in the passenger compartment, and damage to the communication member can be prevented. When the vehicle is tilted backwards or forwards, the connecting member does not come loose, and there is no risk of the feet of rear seat occupants getting caught in the connecting member, resulting in excellent safety.Furthermore, the connecting member is not exposed to the outside. Since there is no such thing, the appearance can be significantly improved.
