Description

[Detailed description of the invention] This invention is a vehicle seat with an armrest, specifically, a mounting structure for a decorative plate that closes off the back side of the armrest storage space in a rear seat bag (passenger car) with an armrest made of wire for the purpose of weight reduction. This is related to.

Conventionally, this type of seat has been made of a wire rod frame body (lower frame line) with S springs, etc. stretched over it, on which support parts, foam materials, and other part materials are placed and covered with a skin to reduce weight. However, as shown in Fig. 6, the armrest B attached to the center of the seat is attached via hinge brackets 11, 11 to angle-shaped reinforcements 10, 10 installed vertically along the left and right ends of the back of the storage space, Since the decorative plate 13 that closes the back of the storage space is fastened to the reinforcements 10, 10 with screws 12, it is not possible to reduce the weight of the sheet by using the angled reinforcements 10, and this wire sheet is Both left and right ends of the seat are fixed to the vehicle body, but since a heavy reinforcement is placed in the center, the weight of the seat makes the seat unstable after it is attached to the vehicle body, and may be affected by vehicle vibrations, etc. There was a risk that the center part would wobble. Moreover, since the decorative board is fixed with screws, it has a drawback that the workability is extremely poor.

Therefore, the purpose of this invention is to eliminate the defects of the conventional product, and its basic configuration is to install a fixed rod made of wire in the vertical direction of the lower frame line made of wire,
A curved locking protrusion is provided in the axial direction of the fixing rod,
This locking protrusion is made to protrude outward from the through hole of the decorative board and is locked with a barb piece, thereby fixing the decorative board.
Therefore, the conventional angular support for attaching the decorative board is no longer necessary, the sheet size can be reduced, and the workability of installing the decorative board can be greatly improved.

Embodiments of the present invention will be described below based on the drawings.

A in the figure indicates the seat (rear seat back).
This sheet A has a conventionally well-known structure in which a spring such as a formed wire is stretched around the lower frame line 1, a foam material a' is placed thereon, and the foam material a' is covered with a skin a''.
B is an armrest, and the bracket 5,
5. It is fixed to the lower frame line 1 via the mounting piece 6 and the like. In other words, the structure is such that the load applied to the armrest B is supported by the lower frame line 1 via the brackets 5, 5, etc. C indicates the vehicle body. In the figure, reference numerals 2 and 2 indicate fixing rods made of wire rods, which are installed in parallel across the top and bottom of the lower frame line 1 by spot welding, etc., with a plurality of rods (as shown in the diagram) with a predetermined gap in the axial direction. The locking protrusions 2', 2' are provided at the top and bottom respectively, and these locking protrusions 2', 2' are formed by bending the fixing rod 2 outward in a curved shape. so that it protrudes from the through hole 3'. The decorative board 3 is a hard and lightweight flat board made of synthetic resin, cardboard, etc., and has a plate at a position corresponding to the locking protrusions 2', 2'.
Elongated through holes 3', 3'... are opened, and (the fourth
), from the back side of the seat A, apply it to the fixing rods 2, 2 so as to close the storage space A, and from the locking protrusions 2', 2'... of the fixing rods 2, 2 through the through holes 3', 3'... The barlets 4 are inserted into the protruding parts 2'' and 2'' and locked therein (Figs. 1 to 3).The barlets 4 and 4' are made by folding the steel wire into a U-shape. Either an engaging stepped portion 4' that engages with the protruding portion 2'' is provided on one side of the bent portion so as to exhibit inward springiness (Fig. 3), or a rod-shaped body (as shown in Fig. 5) is formed. One end of the wire is bent and formed so that it can be inserted across the protrusions 2'', 2'' in the locking protrusions 2', 2' of the left and right fixing rods 2, 2 (Fig. 5). ).

Therefore, in the case of the former bar 4, the protrusion 2'',
2'' to reliably prevent the decorative laminate 3 from falling off, and the latter 4' can be inserted through the left and right protrusions 2'', 2'' at the same time, making it easier to attach the decorative laminate 3. becomes easier.

In the figure, reference numerals 7 and 7 refer to wire mounting rods installed on the lower frame line 1 parallel to the inside of the fixed rods 2, 2, and a supporting rod 8 is installed at the lower part of the housing space A. , 8 horizontally, and a metal plate mounting piece 6 for attaching the brackets 5, 5 to the support rods 8,
is fixed by welding etc.

As described above, in this invention, the armrest is attached to a frame made of wire to which the decorative board is fixed, so the load is concentrated at the lower part of the lower frame line where the armrest is attached, but this part is provided with a reinforcement like the conventional product. It can be reinforced without any stress and can prevent deformation due to load.

That is, the present invention can reinforce the lower frame line without increasing weight by constructing a fixed frame made of a plurality of wires above and below the lower frame line of the armrest attachment part. By fixing the decorative board to this fixed frame, the load applied to the lower part of the lower frame line via the decorative board can be distributed over the entire lower frame line.

In other words, the present invention can reinforce the armrest mounting portion of the wire frame where the load is concentrated, by using the fixed frame made of wire and the decorative plate fixed via the fixing rod, thereby eliminating the problems of the conventional products. Furthermore, since the decorative board can be attached by simply placing the decorative board on the fixing rod and inserting the bar pieces, the installation work can be performed extremely easily and the workability is also extremely good. In addition, since the fixing rod is made of wire and its locking protrusion can be formed simply by bending and forming a part of the fixing rod, the fixing rod itself can be easily formed and can be assembled at the same time as forming the lower frame line. Productivity can be improved.

Thus, the intended purpose can be achieved.
