Problems solved by technology

[0016] If such oozing occurs, then after finishing the foaming and hardening of the foaming raw material Figure 15 (a) the head restraint 107, such as Figure 15 As shown in (a) and 15(b), foaming material occurs at the boundary portion A between the main body portion 102 of the skin 101 and the protruding portion 103 of the skin 101 (that is, the portion where the pinhole is enlarged due to right-angle sewing). The oozing F, the appearance of the headrest 107 is greatly compromised

Embodiment approach ）

[0053] Hereinafter, the headrest which is an example of the foamed molded article for vehicle seats concerning this invention is taken as an example and demonstrated based on specific embodiment. In addition, it goes without saying that the present invention is not limited to this embodiment. In addition, in the drawings of this specification, in order to show characteristic parts easily, constituent elements may be shown with ratios different from those of actual members.

[0054] (overall shape of the headrest)

[0055] figure 1 A headrest for a vehicle seat is shown as one embodiment of the foamed molded article for a vehicle seat according to the present invention. The headrest 1 has a U-shaped or U-shaped metal frame 2 , a foamed resin cushion pad 3 provided around the frame 2 , and a skin 4 covering the entire cushion pad 3 .

[0056] The frame 2 has pillar parts 2a and 2b protruding to the outside of the skin 4, and a connection part 2c connecting the pillar parts 2...

Abstract

The invention aims to prevent resin to ooze from the surface skin of a foaming forming body, such as a headrest, which is formed with a specific shape by enabling resin injected into the surface skin to foam and harden. In the headrest (1) with a buffer pad (3) having the specific shape after foaming and the surface skin (4) covering the buffer pad (3), the surface skin (4) is provided with a main body part (8) covering the buffer pad (3) and an extending part (9) extending out from the main body part (8). The main body part (8) and the extending part (9) are formed by seaming of surface skin parts (4a, 4b, 4c). The boundary part A between the main body part (8) and the extending part (9) is seamed in a curve shape, and a connection part (20) for connecting opposite surface skin parts is arranged on the position close to the outer side of a curve-shaped seaming line (G3). A parta inserted into an opening (K) is carried by the connection part (20).

Description

technical field [0001] The present invention relates to a foamed molded article for a vehicle seat such as a headrest for a vehicle seat and an armrest for a vehicle seat. Background technique [0002] The foamed molded product for a vehicle seat is an appliance for a vehicle seat in which a foamed resin formed into a predetermined shape after foaming is covered with a skin. The molded foam is, for example, a headrest, an armrest, or the like. A headrest is a vehicle appliance that supports the head of an occupant seated in a vehicle seat. An armrest is a vehicular appliance that supports the arms of a seated occupant seated in a vehicular seat. [0003] (Patent Document 1) [0004] Conventionally, according to Patent Document 1, foamed molded articles such as headrests are known. In this molded foam, the skin with built-in pillars is arranged in the molding die, the foamed resin raw material is injected into the skin, and the foamed resin is made to The raw material is...
