Description

[Detailed Description of the Invention] The present invention relates to a guide member that moves a slider member connected to the upper end of the shoulder belt along a guide rail having a bent part provided from the front roof to the middle position of the center pillar. .

Various devices have been proposed for passive belts that restrain and release occupants in conjunction with the opening and closing of the door, but in the conventional type, a slider member moves inside a guide rail provided along the inner surface of the roof side. This caused the belt connected to the slider to move back and forth.

However, in such conventional belts, the slider member is slowly fixed at the front and rear ends of the guide rail, and stable fixation cannot be achieved. Therefore, various locking mechanisms have been proposed for the movable anchor member. There is.

However, it is undeniable that these locking mechanisms have a complicated structure, and furthermore, if the slider is a single member, it is difficult to utilize this structure, and it is necessary to consider it from a completely different perspective. In addition, it was found that the slider member requires considerable strength due to tension when the belt is in the restrained position, and it is necessary to consider stabilizing the slider member from both secure fixation and strength. I became acutely aware of this.

Furthermore, in order to prevent the occupant from hanging when restrained by a belt, a structure was adopted in which the guide rail was lowered to the middle position of the center pillar, and a bent part was formed in the guide rail, and the slider part was improved. We have found that it is a good idea to also consider fixing means that correspond to this.

The present invention is based on the above-mentioned viewpoints, and aims to provide an improved belt guide member that has a simple structure that reliably fixes a slider member to which a belt is connected, and has increased strength when tensioned. In addition to installing a guide rail from the front roof to the middle position of the center pillar,
A stopper is provided at the front end of the roof of the rail, and an anchor is provided at the end on the center pillar side for receiving a slider member and ensuring strength when the restraint belt is suspended.

Hereinafter, specific configuration examples of the present invention will be described in more detail based on embodiments shown in the accompanying drawings. FIG. is the vehicle body, 2 is the door, 3 is the seat, and 4 is the shoulder belt that is pulled out from the emergency field tractor 5 installed on the side of the center side of the vehicle body of the seat 3 and extends diagonally upward across the seat 3; The end is a guide rail 1 provided from the center pillar 9 to the inside of the roof side 8.
Rivet 1 on slider 13 that moves back and forth along 0
It is fixedly attached to a belt attachment hole of a tongue 6 which is removably engaged with a buckle 7a of a stalk 7 which is rotatably attached by 3' so as to be detachable in an emergency.

The slider member 13 includes a response member on its front side, for example, a response rod 16 on the door side as separately proposed by the present applicant, and a holding member 17 corresponding to the response rod on the vehicle body side, and closes the door. The amplifying mechanism 15 is engaged with each other when the door is half open and the amplifying mechanism 15 is operated, but between the door half open and the door fully opened, the engagement is lost and the response member is activated to allow the door to open freely in the state shown in the figure. The end of a drive member, for example, a guard wire 14, which is interlocked and driven via the amplification mechanism 15, is connected to the door 2.
It is constructed so that it can move back and forth in response to opening and closing.

The guide rail 10 is a main part of the present invention, and has a C-shaped cross section as shown in an enlarged view in FIG. Bends forward at the junction with side 8,
It is installed forward along the roof side 8 and reaches the front roof.

There is a slider member 1 at the tip of the roof side rail.
A stopper 12 is provided to prevent the belt 3 from deviating forward and to determine the forward movement point of the belt 4, while an anchor 11 is provided at the final end of the rail on the center pillar side.

As shown in the figure, the anchor 11 has a concave notch 11a in the center, and when the slider member 13 moves rearward, its rivet portion 13' is housed in the concave notch 11a. The aim is to increase the strength against tension of the belt 4.

In this case, the structure of the slider member 13 is as shown in detail in FIG. 3, in which a doglegged member 13a and a short rod member 13b are fastened together with a rivet 13' at the center member to form an inverted Y-shape. It is preferable to provide an enlarged sliding part in the upper end of the rail so that the upper end thereof is fitted into the upper passage of the rail, and the lower leg ends are fitted into the lower side connecting part of the rail. The legs 20 are installed so that the ends of both legs can be expanded and narrowed, and the rail 10 can smoothly pass through the bent portion.

Further, a lead wire 21 connected to a normal alarm device is connected to the anchor 11, and when the slider member 13 is fitted into the anchor 11, the system generates an alarm by removing the tongue 6.

In FIG. 1, reference numeral 18 is a knee pad provided below the instrument panel 19 of the vehicle body in front of the seat, and works in conjunction with the shoulder belt 4 to further ensure the protection of the occupant.

In addition, although the shoulder belt 4 is a diagonal belt in the above illustrated explanation, it can also be applied to a shoulder belt in a three-point belt system at any time. The same effect can be obtained even if the holding member 17 and the holding member 17 are replaced.

Furthermore, an anchor 11, a slider member 13, and a guide rail 1
It goes without saying that the shape of the 0 etc. can be modified as appropriate without departing from the purpose of the present invention.In particular, a rail with a cross-sectional shape in which annular portions having openings facing each other are connected is the most effective and is suitable for driving members. 14 and the slider member 13 are not limited to the front side, but may be connected on the rear side.

In addition to mechanical driving, the driving method may also be an electric driving method using a motor.

The guide member of the present invention is constructed as described above, so that when the door is opened from the closed state, it is pulled forward by the drive member 14 amplified by the amplification mechanism 15, and the shoulder belt 4 is moved from the restraint position to the release position. do.

At this time, there is a stopper 12 at the front end of the roof side rail, which stops the slider member 13 and tilts the stalk 7 with the buckle 7a forward.

On the other hand, when the door is closed from the open state, the slider 13 moves backward, passes through the bent part, reaches the intermediate position of the center pillar 9, and enters the anchor 11 as shown in Fig. 2, so that the shoulder belt is tensioned. This ensures that the vehicle's occupants are restrained while its strength is maintained and guaranteed.

At this time, when the engagement between the tongue 6 and the buckle 7a is disengaged, an alarm is generated via the alarm lead wire 21, and the occupant etc. are notified of this.

In the event that the amplification mechanism is damaged due to a collision or the like, the response rod 16 and the holding member 17 are disconnected from each other, allowing the door to be opened and closed freely.

As described above, in the present invention, the guide rail of the passive belt is installed from the front roof to the middle position of the center pillar, and the shoulder belt is moved, thereby preventing the neck hanging phenomenon caused by the belt during restraint. It is possible to wear the belt comfortably, and the stopper at the front end of the guide rail allows the buckle to tilt forward when retracting, increasing the retraction space for the belt and making it easier for passengers to get on and off the vehicle. By providing an anchor at the side end, it is possible to securely hold and fix the slider part during restraint, and this also ensures sufficient strength against the tension of the restraint belt, increasing the practicality of the passive belt. can be significantly improved.
