SOLUTION: V-shaped grooves 10 and 11 for forming a slit 1 are molded, previously when the pad P is molded, on the inner side of a part of the pad P where the slit 1 is formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile seat (seat) having an armrest or the like provided on a side surface of a seat back (backrest).

[0002]

2. Description of the Related Art In a vehicle seat with an armrest, a support member for supporting the armrest or a stopper for keeping the armrest in a non-use state or a use state protrudes outward from a side surface of the seat back.

The above-mentioned support member or stopper is welded to a side frame of a seat back frame, and the frame is covered with a foam-made pad formed substantially in a bag shape. An opening for letting the outside project is provided. In addition,
The pad is covered by a skin.

[0004] A reinforcing cloth for preventing abrasion of the pad with respect to the frame and the like is integrally formed on the inner surface side of the pad.

[0005] Therefore, it is difficult to expand the insertion opening of the frame provided below the pad outward and insert the frame inside. Therefore, when the support member or the stopper on the frame side is inserted into the pad, the support member or the like becomes an obstacle. Therefore, a slit is formed from the insertion hole of the pad to the lower edge of the pad, and the slit is inserted from the slit. The support member or stopper is inserted into the pad together with the frame in the mouth.

[0006]

Incidentally, the slit is formed by cutting a part of the pad with a cutter after foam molding of the pad. The side frame side of the pad that provides this cut has a uniform thickness throughout,
A slit is formed in the center of the pad in the front-rear direction on the side frame side.

On the other hand, the side frames are made of sheet metal, and are provided with bent portions bent inward at front and rear edges. Further, the side frame side of the occupant support portion, which is the front surface of the pad, is formed so as to bulge forward.

Therefore, according to the conventional product, when the frame is inserted into the pad, the bent portion at the front portion of the side frame bites the pad located on the front side of the slit, and the pad in the bite portion is recessed. However, the surface of the pad may be deformed.

In addition, since there is no positioning when forming the slit with the cutter, it is not possible to provide a cut at an accurate position, and there is also a problem that the support member and the stopper are difficult to enter the insertion opening from the slit.

Therefore, an object of the present invention is to eliminate such disadvantages of the conventional product.

[0011]

In order to achieve the above object, the present invention is characterized in that the conventional slit is formed in a V-shaped groove from the inside to the outside of the pad. And

Therefore, when the slit is formed, since the slit is formed by cutting along the V-shaped concave groove, the pad is thin and the slit is formed at a predetermined position. In addition, protrusions such as support members and stoppers on the frame side can easily enter the pad insertion holes by the concave grooves.

Further, since the depth of the concave groove is gradually reduced from the lower end edge of the pad in the direction of the insertion hole, the workability of cutting by the cutter is good, and the protrusion easily enters.

Further, the slit is formed such that a cut-out direction at a lower end edge of the pad is inclined rearward with respect to a vertical direction of the pad, and a connection point to the insertion port is located at a central portion in the front-rear direction of the side frame. Accordingly, when the frame is inserted, the pad does not bite into the edge of the side frame.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described.
This will be described with reference to the drawings. FIG. 7 shows an automobile seat according to the present invention, in which an armrest (A) is attached to a side surface of a seatback (SB) so as to rotate from an illustrated use state to a non-use state which is a standing state. In the figure (S
C) shows a seat cushion.

The above-mentioned seat back (SB) covers the pad (P) made of foam, the back frame (F) inserted into the pad (P) shown in FIG. 1, and the pad (P). And a bag-shaped skin (not shown).

The above-mentioned pad (P) is foamed into a form as shown in the figure by a mold, and then the side portion (2) is cut by a cutter.
The slit (1) is formed by cutting (cutting) from the lower edge of the lower end (2A) toward the insertion opening (20). The inner surface of the pad (P) is provided with a reinforcing cloth (P ₁ ) integrally formed at the time of molding the pad (P).

The insertion opening (20) has a disk-shaped pedestal (3) welded to the side frame (33) of the frame (F).
The support hole (3), which is an integral part of the stopper (31) and the armrest (A), is inserted into the pedestal (30) in a rotatable manner.
2) is provided. In the figure, (34) is a reinforcing member for integrally connecting the left and right side frames (33), (35) ...
Indicates an S-shaped spring.

The slit (1) is inserted into the opening (20) with respect to the vertical line (1 ') on the side (2) of the pad (P).
Of the pad (P) from the lower edge to the lower edge (2A) of the pad (P). That is, the cutout of the slit (1) at the lower edge of the lower end (24) of the pad (P) is located on the rear side of the lower end (2).

2 to 4 show a slit (1), which is formed along V-shaped concave grooves (10) and (11) provided inside the pad (P). .

The concave grooves (10) and (11) are formed on the inner surface of the side portion (2) of the pad (P) in a V-shape toward the outer surface when the pad (P) is formed. Groove (1
The slit (1) is formed by cutting the bottom (12) of (0) with a cutter.

The depth of the concave grooves (10) and (11) is gradually reduced upward.

FIGS. 5 and 6 show a state in which the back frame (F) is inserted into the pad (P), and the pedestal (3) of the back frame (F) is inserted through the insertion hole (20) of the pad (P).
0) is exposed, and the stopper (31) protrudes outward.

The above-mentioned back frame (F) is inserted into the pad (P) from the lower opening of the substantially bag-shaped pad (P). At this time, the pedestal (32) projecting to the outside of the back frame (F) has a V-shaped groove (10) (11).
The slit (1) is inserted along the base (3
It expands with the insertion of 2). Therefore, the stopper (3
2) smoothly passes through the slit (1) and fits in the pad (P) insertion opening (20) together with the pedestal (32).

[0025]

According to the first aspect of the present invention, since the slit is provided in the V-shaped concave groove, the cut thickness of the pad is small, and the workability of the cut can be improved. Since this serves as a guide, a slit can be provided at an accurate position.

According to the second aspect of the present invention, since the protrusion of the back frame can be inserted along the V-shaped concave groove, the protrusion can be easily inserted without damaging the pad.

According to the third aspect of the present invention, the pad is not deformed by the insertion of the protrusion.
