Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) This invention relates to a drive type passive belt.

(Prior Art) Conventionally, in a passive belt in which a retractor is fixed to a lower portion of a seat and one end of a shoulder belt fed from the retractor is coupled to an anchor point on the vehicle body side, the passive belt is disclosed in, for example, JP-A-60-71353. As described in Japanese Patent Publication, there is a drive type.

The outline of the drive type passive belt has a structure in which a shoulder belt extended from a retractor is coupled to a slider that can be slid from a center pillar region to a front pillar region along a side roof by a drive device.

(Problems to be solved by the invention) As described above, the slider to which the shoulder belt is coupled is switched between the use state in which the occupant is restrained by sliding from the center pillar region to the front pillar region and the non-use state in which the restraint is released. As an alternative, the slider comprises a coupling portion 103 (buckle) to which the tongue 101 of the belt is coupled and a slide portion 107 slidably mounted on the guide rail 105 as shown in FIG.
A concave space 109 is formed between 03 and the slide portion 107. Therefore, for example, in the pillar corner portion 115 that extends from the region of the side roof 111 to the center pillar 113, the pillar corner portion 11 has a small corner angle.
At 5, the posture of the slider 117 changes, and the connecting portion 103 comes closer to the guide rail 105 side as shown by the chain line.

In such a case, for example, if an occupant accidentally puts a hand on the pillar corner portion 115 or inserts a foreign substance by mischief or the like, the recessed space 109 may cause pinching.

Therefore, in the pillar corner portion 115, a measure is taken to prevent entrapment by adding a brace, or by taking measures such as increasing the corner angle with a weather strip, but the appearance becomes worse, and moreover, The number of steps for adding braces and the like increases, which is not desirable in terms of work man-hours and cost.

In view of such a conventional example, an object of the present invention is to provide a drive type passive belt capable of preventing entrapment of foreign matters and the like by a simple device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is a guide that is bent from a substantially vertical center pillar and is extended along a side roof to a front pillar region in front. The rail has a slide portion slidable along the guide rail by a driving device, and a recessed space in which inner wall surfaces of the slide portion face each other along the center pillar and the side roof, and extends outside the guide rail. And a slider formed of a connecting portion that is coupled to the shoulder belt that is drawn out from the retractor, and the connecting portion side that forms the recessed space,
A protrusion protruding along the guide rail side is provided to reduce the clearance between the center pillar and the side roof.

(Operation) According to such a drive-type passive belt, even if a hand or a foreign substance is mistakenly inserted into the slider on the pillar corner portion, for example, it is eliminated by the protruding portion, and the pinching does not occur.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2.

In the figure, 1 is a front seat fixed to the floor panel 3,
Reference numerals 5 respectively denote passive belts for restraining the occupant of the front seat 1.

The passive belt 5 has a structure in which a two-point lap belt 9 is combined with the shoulder belt 7, and the lap belt 9 is fed from a lap belt retractor 11 fixed to the vehicle body side, and the tongue 13 at the tip is The inner buckle 15 provided on the seat 1 side is detachably coupled to each other.

The shoulder belt 7 is unreeled from a shoulder belt retractor 17 that is fixed to the vehicle body side, and the tongue 21 on the tip side is
Is coupled to slider 19.

The slider 19 is a connecting portion that constitutes a shoulder buckle that is detachably connected to the tongue 21 of the shoulder belt 7.
23 and a slide portion 25 extending from the connecting portion 23 into the guide rail 27.The connecting area connecting the slide portion 25 and the connecting portion 23 is provided with a first portion so that the pillar corner portion 27a can slide without any hindrance. As shown in FIG. 1, a concave space 26 is formed along the center pillar 29 and the side roof 31 so that the inner wall surfaces 26a, 26a face each other. The slide portion 25 is mounted slidably along the guide rail 27. The guide rail 27 is arranged from the area of the center pillar 29 along the guide rule 31 to the area of the front pillar 33, and is fixed to the vehicle body side via a plurality of brackets 30.

On the other hand, the guide rail 27 is provided in the connecting portion 23 area of the slider 19.
A protrusion 35 that projects toward the side is provided.

The protruding portion 35 has a shape extending downward from the base portion of the connecting portion 23 at the position shown in FIG. 1, and is set so that the clearance margin α from the base portion of the protruding portion 35 to the center pillar 29 is set to be small. I'm trying not to get up.

The slide portion 25 of the slider 19 is connected to the motor 39 of the drive device 37.
The drive tape 41 is connected to the drive tape 41, and is slidable along the guide rail 27 as the drive tape 41 moves.

In the drive type passive belt 5 configured as described above, the slider 19 is slid along the guide rail 27 to restrain the occupant (a solid line in FIG. 2).
Then, the unmounted state (chain line in FIG. 2) can be obtained.

On the other hand, when the slider 19 slides, the pillar corner 27
In a, for example, even if a hand is accidentally inserted or a foreign object is inserted by mischief or the like, the foreign matter is removed by the protrusion 35 and no pinching occurs.

Further, even if a foreign matter or the like is inserted in a region outside the pillar corner portion 27a, the foreign matter or the like is removed by the protruding portion 35 and no pinching occurs.

[Effects of the Invention] As described above, according to the movable passive belt of the present invention, the protruding portion protruding toward the guide rail side prevents the foreign matter from being caught in the connecting portion area having the recessed space. be able to. In addition, the appearance quality is not impaired.
