がある。(Prior Art) Recently, various so-called automatic belt devices have been proposed in order to automate the loading and unloading of seat belts and protect the occupants from obstacles such as accidents. As a mode, as shown in FIGS. 8 and 9, a shoulder retractable and retractable in an emergency lock type retractor (3) installed on the side of the seat (2) on the center side of the vehicle body (1). belt
(4) or a guide rail in which the pull-out end of the waist belt (4) 'is provided on the roof side (5) of the vehicle body (1) or the inner surface of the door (6)
(7), (7) 'is slidably provided along the belt guiding slide members (8), (8)' by means of sewing or the like, and the slide members (8), ( 8) 'is connected to the tip of a tape-shaped drive member (10) that is forced to slide in the longitudinal direction by a drive mechanism (9) that drives forward and reverse in response to opening and closing of the door (6), and the slide member ( 8), (8) ′ to the guide rail (7),
There is a configuration in which the belt is retracted when the occupant gets in and out of the vehicle so that the passenger can easily get in and out of the vehicle by transferring between the release position shown by the two-dot chain line in the front along (7) ′ and the restrained position shown by the solid line in the rear.

耐久寿命が短縮される問題があった。(Problems to be solved by the invention) However, since the tape-shaped driving member used in the conventional automatic belt device of this type has a synthetic resin coating formed on the outer surface of a long narrow metal tape. When the guide rails (7), (7) 'have poor flexibility and have a complicated shape that follows the curved surface of the vehicle body and a tape-shaped drive member is passed through the guide rails (7), (7)', the sliding resistance increases and the load increases, driving There is a problem that the durable life of the member is shortened.

この点について更に改善すべき余地が残されていた。In order to overcome such inconvenience, the present inventor has devised to use a tape-shaped drive member with improved flexibility by burying a plurality of metal twisted wires inside the synthetic resin narrow tape along the longitudinal direction. However, the tape-shaped drive member is
When connecting this to the tip of the slide member, since the projection formed on the slide member side is fitted into the long hole provided at the tip of the tape-shaped drive member and connected,
In the tape-shaped driving member having the metal stranded wire embedded therein, the peripheral portion of the connecting hole is more likely to be deformed than in the case where the metal tape is built in, and the protrusion on the slide member side is abruptly detached in the curved portion of the guide rail. There is a problem that the slide member moves badly or deforms and it is supported by the groove of the guide rail,
There was room for further improvement in this regard.

その後の実験で判明した。Further, in the case of the tape-shaped driving member in which the metal twisted wire is embedded, twisting occurs in the entire tape-shaped driving member due to the twisting direction of the twisted wire or the number of wires, which causes the sliding resistance in the guide rail. Subsequent experiments revealed that it contributed to the increase.

という効果がある。(Effects of the Invention) As described above, the automatic belt driving device of the present invention is provided in the guide rail attached to the vehicle body by connecting the long tape-shaped driving member to the slide member supporting one end of the occupant restraining webbing. In an automatic belt driving device, which is slidably inserted and which transfers the slide member between a release position and a restraining position along a guide rail by push-pull sliding of the tape-shaped drive member, , A plurality of metal twisted wires including metal twisted wires twisted in opposite directions at least symmetrically with respect to the tape center line and embedded in a synthetic resin tape in parallel at a required interval, and A connecting metal fitting having a connecting hole capable of fitting with the protrusion formed on the slide member is fixed to the exposed portion of the twisted wire of the tape-shaped drive member, and the slide portion is connected through the connecting metal fitting. Since the tape-shaped driving member is connected to the material, the tape-shaped driving member itself is easily bent along the shape of the guide rail due to the material characteristics of the synthetic resin tape, and the metal stranded wire embedded inside Since the twisting direction of the belt is in the opposite direction, no twisting occurs, the sliding in the guide rail is smooth, and the reinforcement of the belt drive is extended and operated by sufficient reinforcement due to the action of the metal twisted wire. It has the excellent effect of maintaining the certainty of. Moreover, according to the present invention, since the slide member is connected to the tip of the tape-shaped drive member via the connecting metal fitting, the peripheral edge of the connecting hole of the connecting metal fitting is sufficiently reinforced and the bonding strength between the two is maintained. The effect is that movement within the guide rail can be performed smoothly.
