Description

[Detailed Description of the Invention] The present invention relates to a webbing latching device for latching the webbing of a seat belt device for restraining and protecting an occupant in an emergency such as a vehicle collision.

In light of the decline in the rate of wearing seatbelt devices, 1 makes it easier for occupants to wear them.
Various semi-passive seat belts have been proposed that allow the seat belt to be worn semi-compulsively.

These seat belt devices are arranged so that the occupant can easily attach the webbing, which is a restraining member, or
The webbing can be automatically attached to the occupant by a simple operation by the occupant.

However, compared to passive seat belt devices that automatically attach the webbing to the occupant using the driving force of a motor, the webbing moves while being attached to the occupant's upper body while sliding. This may cause problems such as preventing passengers from getting on and off the vehicle freely.

In consideration of the above facts, the present invention improves the ease of wearing a semi-passive seat belt device by making it possible to hook the middle part of the webbing as needed, and also makes it extremely easy to wear even in a normal seat belt device. The purpose is to make it possible to comfortably attach and release webbing.

In order to achieve the above object, a webbing latching device according to this invention) rotatably supports a hook on which an occupant restraint webbing can be latched, and this hook is stopped at the webbing latching position. A stopper is provided, and this stopper releases the stop in response to one predetermined signal, makes the hook rotatable, and releases the webbing from being wrapped around it.A plurality of the hooks are provided around the rotation axis, and the stopper is pulled from the stopper at each position. It can be stopped.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the webbing latching device 10 has a housing 12 that is thin-walled and hollow, and a supporting shaft 14 that is hung around the webbing latching device 10.
This allows the hook ring 16 to rotate.

Four arms 18 protrude in the radial direction from this hook ring 16, and a hook 20 is connected to the tip of each arm 18 in a direction perpendicular to the arms.

Here, when the spindle 14 is pulled and rotated 14 times, the hook 20 is moved approximately 90 degrees from the position directly above the spindle 14, as shown in FIG.
During the 0 degree rotation, it protrudes to the outside through a slit 22 formed in the housing 12.

Therefore, when the hook 20 protrudes from the slit 22 to the outside, the middle part of the moss webbing 24 can be hooked, and when the hook 20 is rotated directly below the support shaft 14, the webbing 24 can be hooked. The latching portion is prevented from moving together with the hook 20 by the housing 12 near the slit 22 and remains, so that the latching to the hook 20 is released.

A disk 26 is fixed to the support shaft 14, and four cylindrical grooves 28 are bored in the circumferential portion of the disk 26, corresponding to the hooks 20 of the hook ring 16, with their axes oriented in the radial direction. ing.

A stopper device 30 can be freely engaged with and detached from this cylindrical groove 28.

This stopper device 30 includes a solenoid 32 . fixed within the housing 12 . Plunger 34 actuated by this
and the spring support rod 35 protruding from the housing 12 (the stopper 3B is urged in the direction away from the solenoid 32 by the urging force of the compression coil spring 36 installed therein).
It is made up of.

The plunger 34 is connected to a seating seat (not shown) for the occupant to detect the seating state of the occupant.
is energized to draw the plunger 34 together with the stopper 38, causing the stopper 38 to escape from the cylindrical groove 28 of the disk 26.

The plunger 34 is then deenergized after an appropriate period of time passing through a delay circuit (not shown).

Next, an embodiment in which this webbing latching device 10 is applied to a seat belt device will be described with reference to FIG. 34.

The webbing latching device 10 is embedded in and fixed to the roof 40 of the vehicle, and its slit 22 faces toward the inside of the vehicle.

In addition, a buckle device 4 is provided on the inside side of the passenger seat 42.
4 is fixed, and the tongue plate 46 can be attached to and detached from this buckle device housing.

This tank plate 46 has a webbing 24 for restraining the occupant.
One end of the webbing 24 is locked, and the other end of the webbing 24 is folded back by a through ring 50 attached to the upper part of the center pillar 48 and then wound into a winding device 52 provided below the center pillar 48. ing.

Here, the winding device 52 is structured to unwind the webbing 24 by a biasing force and to abruptly stop the unwinding of the webbing 24 in case of a vehicle emergency.

Therefore, if the occupant opens the door 54 and sits on the seat 42, then by engaging the tongue plate 46 with the buckle device 44, the occupant's upper body is placed between the webbing 24 and the seat 42, and the occupant is restrained by the webbing 24. It is now possible to become

Note that it is also possible to provide a waist restraint webbing that connects the tongue plate 46 and the opposite side of the seat.

In the embodiment configured as described above, when the occupant exits the vehicle from the restrained state shown in FIG. By doing so, the middle part of the webbing 24 can be hooked to the hook 20 of the hooking device.

Therefore, during this latching operation (as shown in FIG.
The passenger can get on and off the vehicle without having to leave the vehicle.

Therefore, after riding the vehicle again, the occupant only needs to sit on the seat 42, and a switch (not shown) provided on the seat 42 detects that the occupant is seated, and the plunger 34 and stopper 38 are driven to excite the solenoid 32. 2
6. Cancel the suspension.

As a result, the hook ring 16 is rotatable and the webbing 2
The hook ring 16 rotates counterclockwise in FIG. 1 due to the urging force of the take-up device 52 acting on the webbing, so that the middle part of the webbing separates from the hook 20 and returns to the sheet 42 as shown in FIG. It is possible to reduce the distance between the two and place the seated occupant in a restrained state.

After the webbing 24 is separated from the hook 20), the stopper 38 again contacts the outer circumference of the disk 26 by the biasing force of the spring 36 to provide frictional resistance to the rotation of the hook ring 16, and the hook 20 moves along the two-dot chain line in FIG. Since the trowel protrudes from the slit 22 of the housing 12 as shown, it can be used for the next webbing hooking operation.

Further, when the middle part of the webbing is wound around the next hook 20, the hook 20I is rotated by the tension of the webbing and reaches the stop position where the stopper 38 is inserted into the cylindrical groove 28, as shown by the solid line position in FIG. It is rotated.

In the above explanation (Figures 3 and 4), the ordinary seat belt device 1 was explained, but the through ring 50 and the winding device 52
By providing the locking device 10 on the door 54, a semi-passive seatbelt device can be obtained, and by attaching the locking device 10 to the upper portion of the door 54, the operability is further improved.

As explained above, the webbing latching device according to the present invention is capable of latching the middle part of the webbing, which improves the ease of wearing semi-passive seatbelt devices, and makes it easier and more comfortable to unfasten and release the webbing when using a normal seatbelt device. It has the excellent effect of making it possible to provide the same function as a semi-passive seat belt.
