Description

[Detailed description of the invention] The present invention relates to a guide hanger for a safety belt, and more specifically, to a guide hanger for guiding an automatic belt that reciprocates between a restraining position and a releasing position by the operation of a drive member in response to the opening and closing of a door. It is.

Automatic belts that automatically restrain or release occupants in response to the opening and closing of a door using the reversible operation of an electric motor or mechanical drive source have recently been researched in various fields, and efforts are being made to put them into practical use. As is common in this type of automatic belt system, the restraint belt is inserted through a belt guide hanger attached to the rear end of the drive member, and its transfer is achieved by the reciprocating movement of the guide hanger by the drive member. .

Such conventional automatic belt guide hangers (hereinafter simply referred to as hangers) generally belong to belt systems that include automatic belts that restrain the shoulders and waist of occupants, and adjustment belts connected to these automatic belts, and are attached to vehicle bodies such as doors. It is separate from the drive guide system that includes an electrical or mechanical drive source that is attached to the car body assembly line, and it is desirable for the work process to install it on the car body assembly line. Most of them are fixed to a slide member fixed to the rear end of a drive member made of guard wire, etc.
Therefore, when equipping a vehicle with an automatic belt system, even if the drive mechanism for sliding the slider is housed inside the door, it is necessary to use a belt device that includes the slider drive mechanism and a belt retractor, etc. The belt must be inserted into the hanger after it is assembled into a vehicle or installed with a drive member on the door, which is a major obstacle in installing automatic belts.

In addition, when the number of times the automatic belt is used increases and it becomes necessary to replace it due to aging, etc., the drive member to which the hanger is fixed must be removed from the door and repaired each time. However, the installation of the hanger requires a separate tool, which is inconvenient as the tool must be kept nearby during installation.

Therefore, the inventor of the present invention focused on the problem with the conventional belt guide hanger installation, and in order to correct and improve the problem, a locking part is formed on either the slide member or the guide hanger, and the locking part is formed on the other member. We have proposed a configuration in which the guide hanger can be attached to and detached from the slide member while the belt is inserted therein by providing an engagement hole into which the engagement portion can be fitted.

However, even though the above-mentioned proposal greatly improves the installation of the guide hanger, there is a difficulty in the operability for attaching and detaching the guide hanger, and a simpler and more reliable operability has been desired.

That is, the present invention further improves the operability of the guide hanger mechanism according to the above configuration, and also enables easy separation and connection without using any tools, thereby making it easy to attach, detach, and replace the hanger. The purpose of the present invention is to provide a novel hanger.

The hanger of the present invention, which is distantly related to this purpose, has a base body having a belt insertion guide section such as a guide roll at the bottom, and a slide member normally fixed to the rear end of an automatic belt drive member is inserted through the base body to connect the two. However, it is characterized by a structure in which a pin member is housed, which is released from the slide member by spring force and disconnected by pressing or sliding the operating part.

Hereinafter, embodiments of the hanger of the present invention will be described in more detail with reference to the accompanying drawings.

Fig. 1 shows an example of an automatic belt system using the hanger of the present invention. One end is sewn to a tongue 6 that is inserted into and removed from a buckle attached to the upper part of the open side, and the other end extends diagonally downward across the seat 3, becomes a shoulder belt 4a, and is folded back by a connecting ring 7. The waist belt 4b is inserted through the hanger 8 according to the present invention, and its end is fixed to an anchor 9 fixed to the lower end on the door opening side.

On the other hand, the tip of an adjustment bell (10) pulled out from a known emergency locking retractor (11) installed at the lower part of the center side of the vehicle body of the seat (3) is sewn into the connecting ring (7) inserted in the middle of the automatic belt (4). An automatic belt system is configured, which is fastened to the belt when the door is opened and can be automatically adjusted as needed in response to changes in belt length when the door is opened and closed.

In the figure, reference numeral 14 denotes a drive member for transmitting forward and reverse rotation of a known electric or mechanical drive source 13 in response to the opening and closing of the door, and a slide member fixed to the rear end of the hanger 8 of the present invention. are connected to each other, and the hanger 8 is reciprocated along the guide rail 15 on the inner surface of the door.
is shifted between the restraint position and the release position, providing an automatic restraint action by an automatic belt.

Note that 12 is a buckle connection reinforcing member when the door is closed.

In the automatic belt system configured as described above, the hanger 8 that inserts the automatic belt 4 and connects to the drive member 14 side forms a main part of the present invention, and an example of its structure is shown in the second example. As shown in FIGS.

That is, as is clear from the figure, the hanger 8 is composed of a lower belt system connection section that connects to the automatic belt 4 and an upper drive system connection section that connects to the drive member 14 side. A guide roll 20 is rotatably gripped and pierced by a support member 19, 19' extending from the base 17 at the lower belt system connection part, forming a belt insertion part to connect the roll 20 and the base 17. The hanger 8 and the automatic belt 4 are connected by inserting the automatic belt 4 shown in FIG. 1 into the insertion gap between them.

Of course, the guide roll 20 in this case is not limited to the rotatable roll shown in the figure, and may be sewn onto the end of the automatic belt 4 as long as a belt insertion portion is formed.

On the other hand, on the upper drive member connection side including the hanger base,
A pin member 18 whose tip is inserted into and removed from the slide member 16 at the rear end of the driving member 14 in the base space surrounded by the upright peripheral wall exposes its head to the base peripheral wall surface and is inserted into the guide roll 20 on the lower side. The pin member 18 is horizontally installed in a substantially parallel state, and the pin member 18 has a shape suitable for swingingly attaching and holding the hanger 8 to the slide member 16, and has a pair of pin receivers 21 that are erected from the base surface. .21' is inserted and supported through the pin hole 22.22', and a locking recess is provided between the pin receiver 21 on the side closer to the rear end and the inner surface of the head, which is further provided around the rear end side. A compression spring 23 is interposed between the large-diameter flange 24 and the inner surface of the large-diameter flange 24, and is biased toward the right escape direction in the figure.

Note that the space between the pair of pin receivers 21 and 21' forms a gap into which the slide member 16 fixed to the drive member 14 is fitted, and when the hanger 8 is connected to the drive member 14, it is shown by a two-dot chain line. The slide member 16 is inserted between them as shown in FIG. This is what we aim to do.

Next, 25 in the figure is the locking recess 2 of the pin member 18.
The rear end 25b is a locking member consisting of a lever that engages and disengages from the fulcrum 26, and the front end 25a is exposed through an opening 28 provided on the surface of the base 17, serving as a pressing operation part, and is always on. , the rear end portion 25b of the locking member is connected to the locking recess 2 of the pin member 18.
4 is urged by a spring 27 in the direction of locking.

Therefore, in normal times, the rear end 25b of the locking member 25
is locked in the locking recess 24 of the pin member 18 and the pin member 18
When the slide member 16 is present, the two are connected through the pin insertion hole 16a of the slide member 16. However, when pressing the pressing operation part in the opening 28 against the spring 27, the pin member 18 is pushed out. The rear end 25b of the locking member 25 consisting of a lever is removed from the locking recess 24 of the pin member, and the pin member 18 is released by the biasing force of the interposed compression spring 23. The slide member 16 is caused to escape to the right in the figure, and the connection with the slide member 16 is released.

Note that the area of the opening in the pressing operation portion is preferably small if the operation can be performed with the tip of a toe or finger.

Next, to explain the operation of the embodiment as described above, first, when connecting the hanger of the present invention to the drive member side, a drive guide system that responds to door opening/closing is attached to the vehicle body 1 or the door 2, and the rear end of the drive member The slide member 16 which is
1.21', each pin L22.22'
, 16a are aligned, the pin member 18 is pushed in from one side of the base body in the direction of arrow A against the compression spring 23, and is penetrated so that the rear end 25b of the locking member, that is, the lever 25, is inserted into the pin member 18. Once the front end 25a is locked in the locking recess 24, the locked state is maintained by the spring 27 that pushes up the front end 25a via the fulcrum 26 of the lever, allowing the two to be connected.

On the other hand, when trying to break the connection between the two,
If the front end 25a of the lever, which is a pressing operation part, is pressed with a toe or fingertip in the direction of arrow C through the opening 28, the lever 25, which is a locking member, will move around the fulcrum 26 at the rear end 25b while resisting the biasing spring 27. is moved upward and removed from the locking recess 24 of the pin member 18, leaving the pin member 18 in a free state,
The pin member 18 is moved in the direction of arrow B or removed from the base body 17 by the return force of the compression spring 23, and the slide member 16
It is separated from the pin insertion hole 16a.

In this way, the slide member 16 becomes detachable, and the hanger is separated from the drive member side.

FIGS. 4 to 6 show another embodiment of the hanger of the present invention, in which the operating section is operated by a sliding method, whereas in the previous embodiment, the operating section is a push operation type.

Although the model is different in the embodiment of the present invention, a gyrtrol 20' for guiding the belt is provided at the lower part as described above, and a pin member 18' is attached to the base body 17' by a compression spring 23 in the ejection direction at the upper part. , that is, it is biased toward the right in FIG. 4 and placed horizontally.

However, in this case, the E-ring 29 is fitted onto the pin member 18', and the compression spring 23' is interposed between this and the rear side 30 of the pair of pin receivers 30, 30'. In particular, the locking member 25' is formed as a flat locking plate having an elongated hole 31, as clearly shown in FIGS. 5 and 6, and the pin member 18' is inserted through the elongated hole 31.
is inserted through the pin member 18' and is urged upwardly by the plate spring 27' disposed at the bottom to push the lower side of the elongated hole 31 into the pin member 18'.
The pin member 18' is inserted into the locking recess 24' and locked.
Extraction in the direction of escape is prevented.

A protrusion 32 is formed in a part of the flat locking plate 25', and a protrusion 32 is attached to the protrusion 32.
By fitting the cap 33 provided with the cap 4, an operating section is created which pushes and slides the locking plate 25' in the direction of the arrow.

In this embodiment as well, the operation of connecting and separating the hanger 8' and the slide member 16 of the drive member 14 is substantially the same as in the previous embodiment, and the pressing operation in the previous embodiment is replaced by a sliding push-down operation. , and pin member 18'
only moves relatively upwardly within the elongated hole 31 of the locking member 25' and releases the locking action of the pin member 18'.

Thus, in any of the above cases, the hanger and the slide member can be easily connected and separated, and the installation work of the automatic belt system can be greatly improved.

Although the above explanation utilizes the sliding movement of the locking plate 25' of the locking member, the same effect can be achieved by directly pressing the locking member, and this is also included in the present invention. .

Although the hanger of the present invention is particularly effective when used in the automatic belt system as described above, it is also sufficiently useful when used for general belt suspension.

As described above, the hanger of the present invention uses the pin member and the locking member to engage and disengage the slide member and the hanger, and also provides an operating section that presses or slides the operating section. Since the belt system and the drive mechanism system are designed to be connected to and removed from each other, it is easy to assemble the belt system and the drive mechanism system separately, install them on the vehicle, and then connect them to assemble them into an automatic belt system. Not only does it significantly improve the efficiency of assembly work compared to the assembly process, but it also allows the connection to be released with just a slight force of pressing or sliding with a fingernail or fingertip, making it possible to assemble without using any tools.・A device that enables separation, improves the workability of assembly and replacement, has a remarkable effect on streamlining work, and improving productivity, and is highly expected to be used industrially and commercially on automatic belt equipment. It is.
