Description

[Detailed Description of the Invention] The present invention relates to a passive seat belt device, in particular, a passive seat belt device of a type that is provided with a sliding member that moves in a guide rail provided on a roof site rail of a vehicle body, etc. This relates to reinforcement structures.

Conventionally, in such a type of passive seat belt device, as shown in FIG. A driving anchor 3 (or a through guide through which a shoulder belt is passed) fixed by a buckle 5 b is provided with a sliding member 7 that is slidably moved.

In this case, if the drive anchor 3 is not hung down to the height of the occupant's shoulders but extends only to a position slightly lower than the guide rail 1, the drive anchor 3 may be fixed to the drive anchor 3. Since the shoulder belt 4 is provided at a relatively high position, that is, from approximately the bottom of the roof site rail 2 to the floor in the center of the vehicle body, or extends diagonally around the tractor 6, the sliding movement of the sliding member 7 causes the occupant 8 to belt 4b (there is a risk of contact with the head or face).

Furthermore, even if the drive anchor 3 extends to approximately the height of the occupant's shoulders, if it is simply hanging down, the distance between the drive anchor 3 and the occupant's head and face will be narrow, and while the drive anchor 3 is moving, There is a problem in that the occupant is worried about coming into contact with the drive anchor 3.

Therefore, in order to avoid narrowing the space inside the vehicle, the driving anchor 3 is placed on the side opposite to the input direction of the shoulder belt 4, that is, with its tip facing outward from the guide rail 1 provided along the roof sight rail 2. The roof sight rail 2, the door sash, the door glass (not shown), and the like extend approximately along the slopes and curved surfaces of vehicle body members and door members provided on the side of the vehicle interior. It is conceivable that the system could be set up in

However, with this arrangement, the drive anchor 3 extends in the opposite direction to the input direction M of the shoulder belt 4, so if there is a large input to the shoulder belt 4, such as during a vehicle collision, the The shoulder belt 4 moves to the position shown by the chain line in FIG. 1, and the drive anchor 3 is also pulled inward accordingly.

Therefore, there is a risk that the drive anchor 3 may pry open the opening 1a on the lower surface of the guide rail 1 as shown in FIG. 2, or that the guide rail 1 is firmly installed and will not deform. However, there is a risk that the driving anchor 3 may be pulled out from the inside.

Therefore, it is necessary to increase the rigidity of the guide rail 1 by increasing the plate thickness of the driving anchor 3 and the guide rail 1 or by making the cross-sectional shape complicated, which may impair workability or take up space. There were other problems.

Therefore, in the present invention, in order to widen the gap between the drive anchor and the occupant, the drive anchor is positioned so that its tip is directed outward from the vehicle body, approximately along the vehicle body components and door components provided on the side of the vehicle interior, such as the roof site rail, door sash, and door glass. provided so as to extend toward the
Furthermore, in order to prevent the shoulder belt from coming into contact with the occupant's head or face, the tip of the drive anchor is extended so that it is at the height of the back of the occupant in the seated state. During normal use other than when input (load) is applied, the input applied to the crystal rudder belt (
In order to maintain the above-mentioned state, the drive anchor is made of a relatively rigid metal such as a steel plate, and when the drive anchor is in the stopped position with the shoulder belt attached, the drive anchor □Providing a reinforcing structure that prevents the drive anchor from being deformed or pulled inward to open the guide rail, thereby solving the above-mentioned conventional problems. The purpose is to

To this end, in the present invention, a guide rail extending along the roof site rail is provided on the inside of the vehicle interior of the roof site rail formed at the upper edge of the door opening of the vehicle body. A sliding member connected to the device is provided so as to be slidable, and the base end of a drive anchor formed of a rigid member such as a steel plate is fixed to the sliding member, and the tip of the drive anchor is attached to the vehicle body. Extends outward, and extends approximately along a vehicle body member or door member cut into the side part of the vehicle interior, such as a roof sight rail, door glass, pillar, etc., to a position near the height of the back of a seated state. At the same time, the drive anchor is provided so as to be inclined toward the front of the vehicle body as it goes toward the distal end of the base end, and the drive anchor is provided at the distal end of the drive anchor on the center side of the vehicle body, such as on the floor, or the base end is attached to the tractor. When the distal end of the shoulder belt is attached and the drive anchor is at the stop position with the belt attached, it faces the interior side of the drive anchor with a terrestrial gap, and the drive anchor faces the interior side of the vehicle with a terrestrial gap. A structure in which a reinforcement is fixed to a vehicle body member, in which a drive anchor lateral movement prevention surface is formed to cover at least a portion of the drive anchor, and an opening is formed on the front end side to allow the drive anchor to enter and exit. By doing so, it is a distant relative of the above-mentioned purpose.

The present invention will be described below with reference to illustrative embodiments.

Reference numeral 11 denotes a guide rail extending in the longitudinal direction of the vehicle body along the roof site rail 12 on the interior side 12a of the roof site rail 12 formed at the upper edge of the door opening 23 of the vehicle body a. The rail 12 is provided with a sliding member 24 that is slidably movable.

A base end 1.3c of a drive anchor 13 formed of a rigid member such as a steel plate is fixed to the sliding member 24, and its tip 13a extends outward of the vehicle body a and is connected to the vehicle body. Roof sight rail 11, center pillar 22, or door glass (not shown) as a door member
The drive anchor 13 extends approximately along the height of the back of the occupant seated on the seat, and is inclined toward the front of the vehicle body a as it goes from the base end 13c to the tip 13a. It is being

15 is a shoulder belt, and the tip 15a of the shoulder belt 15 is connected to the tip 13a of the drive anchor 13.
The shoulder belt 15 is attached via a buckle 14 fixed to the tip 13a, and the base end of the shoulder belt 15 is attached to the center side of the floor of the vehicle body a or to a retractor (not shown).

The driving device has one end connected to the sliding member 24 of the driving anchor 13.
It consists of a guard wire 16 fixed to the rear end and a forward and reverse motor (not shown) that is operated by turning the door switch ON and OFF.The other end of the guard wire 16 is a forward and reverse motor (not shown).
It is used as a worm of a reversing motor, and the sliding member 24 is moved along the guide rail 11 by opening and closing the door.

Reference numeral 17 denotes a lock pawl provided on the guide rail 11. The lock pawl 17 is detachably engaged with a recess 24a cut in the sliding member 24 of the drive anchor 13. belt! This is done by inputting the door switch when the door 5 is opened.

Reference numeral 18 is a reinforcement which is the gist of the present invention, and is composed of an upper mounting part 18a, a lower mounting part 18b, and a drive anchor housing part 18. The upper mounting part 18a, together with the guide rail 11, is attached by a bolt 19 to the interior side 12.a of the roof sight rail 12, which is a vehicle body member at a stopped position when the shoulder belt 15 is attached, and its lower attachment portion 18b is attached to the center pillar, which is a lower vehicle body member. Bolt 2 to 22
0 and is directly attached and fixed.

When the drive anchor 13 is at the stop position with the shoulder belt 15 attached, a gap 25 between the drive anchor 13 and the terrestrial side surface 13b is formed on the outside side of the vehicle interior of the drive anchor storage portion 18c. A drive anchor lateral movement inhibiting surface 18d is formed which faces the vehicle interior side surface 13b of the drive anchor 13 and is retracted so as to cover a part of the vehicle interior side surface 13b.
The drive anchor 13 is designed to resist the tensile force applied to the drive anchor 13 in the direction toward the inside of the vehicle interior.

Further, an opening 18e is formed at the front end of the drive anchor storage portion 18c to allow the drive anchor 13 to enter and exit.

11a is a flange for attaching an upper attachment portion of the reinforcement 18 that projects above the guide rail 11, and 21 is a spacer.

In the illustration, the drive anchor storage portion 18c has a substantially triangular shape that matches the inclination of the drive anchor 13, but the shape is not limited to this, and the shape can be freely formed as long as the drive anchor 13 can be stored therein. can do.

5 and 6 show another embodiment of the present invention, in which the reinforcement 18' is fixed to the center pillar 22 of the vehicle body. In this example, only the lower end 18a' of the reinforcement 18' is fixed to the center pillar 22, and the upper end 18b' is used as an opening 18C' to allow the drive anchor 13 to enter and exit.

Incidentally, in both of the above two embodiments, the bolt rail 11 is provided on the roof site rail 12 of the vehicle body a, but this can also be applied to an example in which the guide rail 11 is provided on other vehicle body members of the vehicle body a. I can do it.

Moreover, it can be applied not only to the shoulder belt 15 but also to a lap belt.

As described above, according to the present invention, the reinforcement is fixed inside the vehicle interior of one or both of the drive anchor and the guide rail at the stop position when the shoulder belt of the drive anchor is attached, so that the shoulder belt is attached to the drive anchor. Even if a tensile force acts in the mounting direction, that is, toward the inside of the vehicle, the drive anchor contacts the reinforcement and can support the vehicle.

Therefore, it is possible to eliminate the opening of the guide rail opening and prevent the lock from coming off, and since the bolt rail is not deformed, the door can be opened and the drive device such as the guard wire can be opened reliably and The shoulder belt can be released smoothly.

Furthermore, according to the present invention, there is no need to make the guide rail, drive anchor, etc. so large and rigid, so it does not take up much space.

It is also easy to process.

Further, the tip of the drive anchor is inclined from the base end toward the front of the vehicle body, extends to a position near the back height of the occupant in the seated state, extends toward the outside of the vehicle, and is provided on the side of the vehicle interior. Since the shoulder belt extends along the vehicle body parts and door parts, there is no risk of the shoulder belt coming into contact with the occupant's head or face, and there is a wide gap between the shoulder belt and the occupant, so there is no danger of danger. .

Furthermore, the reinforcement fixed to the vehicle body has a drive anchor extending along the vehicle body member and door member, so
The amount of protrusion into the interior of the vehicle is kept to a minimum, so it does not make the interior of the vehicle narrow or give the impression of protrusion.

In addition, when the drive runner enters the reinforcement, there is no need to pull the shoulder belt or drive anchor to the reinforcement side using a drive device such as a geared wire.
This has the advantage that no force is applied to the guard wire to resist the force in the retracting direction, allowing smooth operation.
