Abstract

(57) [Abstract] [Purpose] To prevent damage when a synthetic resin grip body is integrally molded with a core material in a seat back of an automobile seat or an inside of an automobile door. A core material (S) made of a coil spring is embedded in the grip body (1) in a longitudinal direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grip provided on an upper portion of a seat back (back portion) of an automobile seat (seat), an inner surface of a door, and the like.

[0002]

[Prior Art]

 In a conventional grip, as shown in FIG. 3, when a core material (21) made of a metal plate (for example, SK material) is embedded in a grip body made of a synthetic resin such as polypropylene and an external force is applied. There is one that is designed to bend. In FIG. 3, (11) shows a grip portion, (12) shows a fixing portion which is fixed to a seat back with a bolt, and (13) shows an end portion.

[0003]

[Problems to be solved by the device]

 By the way, the core material (21) is housed in a mold and integrally molded with the synthetic resin grip body (P). At that time, since the core material (21) is an SK material, the heat shrinkage rate is different from that of the synthetic resin forming the grip body (P). Therefore, the grip body (P) may be cracked during molding. Further, if the grip body is damaged due to an impact during use, there is a possibility that the synthetic resin may be scattered into small pieces and scattered around the grip body. Therefore, an object of the present invention is to prevent the grip main body from cracking during molding of the grip main body, and to prevent the grip main body from scattering even if it breaks due to impact during use after molding.

[0004]

[Means for Solving the Problems]

 A grip according to the present invention for achieving the above object is characterized in that a core member made of a coil spring is embedded in a longitudinal direction of a synthetic resin grip body.

[0005]

[Action]

 When the grip body is molded integrally with the core material by molding, the synthetic resin of the grip body and the coil spring have approximately the same thermal contraction rate, so the grip body is less likely to crack during molding, and the grip body is shocked during use. When damaged, the synthetic resin forming the grip body does not adhere to the core material consisting of the coil spring and scatter, and since the core material is the coil spring, it does not form a protrusion even if the core material is exposed.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the figure, (1) is a grip portion of a synthetic resin grip body in which a core material (S) is embedded, and (2) is an upper part of the back of the seat back (SB) shown in FIG. 2 by a fastening bolt (not shown). The fixed part of the grip body, which is fixed to the grip body, and (3) are the end parts of the grip body, respectively. The grip body is made of synthetic resin (P) such as polypropylene, nylon, hard vinyl chloride, and hard polyethylene used in this type of grip, and is molded by molding. At the time of this molding, the core material (S) and the fixing member (F) connected to both ends of the core material (S) are housed and integrally molded in the mold.

The core material (S) is a coil spring, which is embedded along the longitudinal direction of the rod-shaped gripping portion (1) and has an outer diameter that is not exposed on the outer surface of the gripping portion (1). To do. The fixing member (F) connected to both ends of the core material (S) uses a plate-shaped steel material in order to improve the attachability to the seat back (SB) side, and the fixing member (F) is fixed to the fixing portion (F). 2), embedded in the end (3).

[0008]

[Effect of the device]

 According to the present invention, since the coil spring is used as the core material, when the grip body is molded, the synthetic resin forming the grip body and the core material have substantially the same heat shrinkage rate. Sometimes the grip body does not crack. Further, when the core material is set in the mold, since the core material is the coil spring, it can be easily set and the workability thereof can be improved. Furthermore, even if the grip body is damaged due to impact during use, the synthetic resin that composes the grip body does not scatter into small pieces, and even if the core material is exposed, it does not bulge and is safe. The property can be improved.
