Description

[Detailed description of the invention] (Field of industrial application) The present invention is a belt guide that guides a seatbelt pulled out from a retractor provided on the floor of an automobile on the center side of the vehicle so as to cross the seat near the side of the passenger's waist. In particular, the present invention relates to a belt guide with a belt stopper for eliminating the feeling of pressure on an occupant due to the belt winding force of the retractor.

(Prior Art) Seat belts are widely used as occupant restraint devices to ensure the safety of occupants in the event of a vehicle collision, and are installed in most vehicles. The problem remains.

Particularly recently, seatbelts equipped with belt retractors have been widely adopted for the purpose of improving operability.
When belts are used for long periods of time, the problem arises that they give a feeling of pressure to the occupants, impairing their comfort, and this is thought to have an effect on the rate of belt wearing. In addition, in the automatic belt device that aims to improve the belt wearing rate,
Since the belt wearing rate is close to 100%, it is considered that resolving the above drawbacks is especially urgent.
Although various studies are currently being conducted in various fields,
I have not yet reached a point where I am fully satisfied.

(Problems to be Solved by the Invention) The present invention deals with the above-mentioned current situation and provides a belt guide that guides the belt pulled out from the retractor, especially on the side of the seat, near the side of the passenger's waist on the way to the pulling out route. Furthermore, by incorporating a belt pressing member that presses the belt against the inner wall of the belt passage hole, the belt winding force of the retractor is arbitrarily eliminated, thereby improving comfort when wearing the seat belt. be.

(Means for Solving the Problems) The structure of the present invention for solving the above-mentioned problems will be explained with reference to FIGS. 1 to 4 of the accompanying drawings. The lower end of a support member 5 of a required length is attached to the side wall of the seat 1 on the center side of the vehicle, the upper end of which is located near the side of the passenger's waist in a seated state, and the upper end of the support member 5 is fixed to the vehicle floor on the center side of the vehicle. A belt guide body 6 is supported for turning the belt 3 pulled out from the retractor 4 across the seat 1, and a belt passing hole 12 provided in the frame 9 is inserted into the frame 9 of the belt guide body 6. In a belt guide in which a guide roller 10 is rotatably housed on the included angle side of the turning direction and wraps around the belt 3 and guides the turning, the belt passage hole 12 is provided in the frame 9 near the guide roller 10. A belt pressing member 13 is provided which presses the passing belt 3 against the inner wall of the passage hole and is movable between a position where the belt 3 is prevented from moving in the longitudinal direction and a position where the belt 3 is allowed to move in the same direction. The pressing member 13 is provided with an actuating portion 15 outside the frame 9 for displacing the pressing member 13 between the two positions,
The belt pressing member 13 is configured to be biased by a spring 17 in the belt releasing direction which is the same direction as the belt pulling out direction from the retractor 4.

(Function) In the belt guide with belt stopper of the present invention having the above configuration, when the occupant operates the actuating section 15 while the belt is attached and moves the belt pressing member 13 to the belt pressure contact position, the belt 3 is Pressing surface 14 of belt pressing member 13 and belt passage hole 1
Since the retractor 4 is sandwiched between the inner wall of the belt 2 and its longitudinal movement is prevented, the winding force of the retractor 4 acting on the belt 3 disappears and does not act on the occupant restraint part, so there is no feeling of pressure. The feeling of wearing the belt is greatly improved. Furthermore, when the belt is detached, the belt pressing member 13 is automatically returned to the non-pressing position by the urging force of the spring 17 by slightly pulling the passenger restraining portion of the belt 3 in the direction in which the retractor 4 is pulled out, and the entire belt 3 is Since the retraction force of the retractor 4 acts on the retractor 4, the belt 3 is automatically retracted and stored in the retractor 4 simply by releasing the belt 3.

(Embodiments) Hereinafter, specific embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 shows a part of the seat belt to which the belt guide of the present invention is attached, and FIG. 2 shows another embodiment of the seat belt to which the same belt guide is applied.

In FIG. 1, the belt guide main body 6 has a built-in belt stopper mechanism, and the upper end of the support member 5 is fixed to the side surface of the seat 1 with a suitable attachment member such as a bolt so as to be located near the side surface of the passenger's waist. The belt 3, one end of which is wound around a retractor 4 attached to the vehicle floor or driveshaft tunnel (not shown) on the side of the seat 1, passes through the belt guide body 6 and runs horizontally over the seat. It is cut and placed.

In addition, in FIG. 2, the lower end of the support member 5 of the belt guide body 6 is rotatably attached to the side of the seat 1 by a pivot, and is connected to the tilting arm 7 of the seat back 2 via a link 8. When the seat back 2 is tilted, it swings in conjunction with the seat back 2, and when the seat back 2 is tilted forward, the belt 3 may be caught between the seat 1 and the seat back 2, or prevent the seat back 2 from tilting forward. It's become like I can't stand it.

Therefore, the main part of the present invention resides in the main body structure of the belt guide device arranged as described above, and the third part is
An example thereof is shown in the figure and FIG.

3 is a cross-sectional view taken along the line X-X in FIG. 4, seen from above, and FIG. A passage hole 12 is formed inside the passage hole 12, close to the inlet side of the belt 3 pulled out from the retractor 4, and rotatably parallel to the belt 3 in a direction transverse to the belt traveling direction. a pin 16 supported between the upper and lower walls; and a plate-shaped belt pressing member 13 having a belt pressing surface at its tip that is fitted into and fixed to the pin 16 and rotates integrally with the pin 16.
A guide roller 10 is provided close to the outlet of the belt 3 and rotatably guides a pin 11 supported between the upper and lower walls of the passage hole 12 in a direction in which the belt is pulled out. A recess 9a is formed in the inner wall of the belt passage hole 12, facing the belt pressing member 13 with the belt 3 in between, and the belt pressing member 13 can be rotated by turning the knob 15 at the upper end. The belt pressing portion 14 presses the belt 3 between the recess 9a and the belt 3. In addition, the belt pressing member 13 normally moves in the direction in which the recess 9a and the belt pressing surface 14 are separated from each other, that is, the belt pressing surface 14 is directed in the direction in which the belt 3 extends from the retractor 4, that is, in the direction of arrow A in FIG. The spring 1 is rotated along the guide roller 10 in the direction of the guide roller 10.
It is biased at 7.

FIG. 5 shows another embodiment of the present invention, and FIG.
The belt pressing member 13 of the embodiment shown in FIG. 4 is replaced with a cam-shaped pressing member, and this is a cross-sectional view of the apparatus seen from above, similar to FIG. 3.

Next, the operation of the belt guide of the present invention having the above structure will be explained.

First, as shown in FIGS. 1 and 2, a retractor 4 is fixed at one end to the upper side of the vehicle, and is provided on the side of the seat 1 on the center side of the vehicle, crossing over the seat 1.
A two-point belt system in which a belt guide with a belt stopper of the present invention is placed near the side of the passenger's waist in close proximity to the retractor 4 of the diagonal belt 3, the other end of which is wound and stored in the vehicle; A continuous shoulder-to-shoulder belt with one end attached, and a retractor 4 with one end attached to the side of the seat 1 on the center side of the vehicle.
A three-point belt consisting of a retractable belt 3, which is wound around and stored in the belt and whose other end is sewn to a ring inserted through the middle part of the single belt, is retracted close to the retractor 4 near the side of the passenger's waist. In a system in which a belt guide with a stopper is arranged on the belt 3, when the occupant first puts on the seat belt, the belt length is automatically adjusted by the belt winding force of the retractor 4, and the seat belt is fitted to the occupant.

At this time, the belt 3 is always in a state of attracting the occupant toward the seat bag 2 with a constant tension due to the winding force of the retractor, giving the occupant a feeling of pressure.

In this state, when the occupant moves the knob 15 and rotates the belt pressing member 13 to the position shown by the two-dot chain line in FIG. The belt 3 is sandwiched between the recess 9a and the belt 3 is prevented from moving in the longitudinal direction, thereby preventing a feeling of pressure due to the winding force. Therefore, the retraction force generated by the retractor disappears in this portion and is not transmitted to the occupant restraint portion, thereby preventing a feeling of pressure and greatly improving the feeling of wearing the belt 3.

Next, the belt pressing member 13 is released from the state of preventing the belt 3 from being caught. When the belt 3 extending across the seat from the belt guide body 6 with a stopper is slightly pulled in the pulling direction, the belt pressing member 13 is released. The belt pressing member 13 is rotated in the same direction by the frictional force with the belt 3 and released so that the belt can be moved in the longitudinal direction, and the belt pressing member 13 is urged toward the release side (in the direction of arrow A) by the spring 17, and is automatically In order to return to the original position before the belt was pressed, the winding force of the retractor 4 acts on the entire belt 3,
The belt 3 is rolled up and stored.

In this embodiment, the knob 15 is provided on the upper part of the pressing member 13 as described above as an actuating part for moving the belt pressing member 13 to the belt pressing position.
Although this is done manually, it is also possible to automatically move the belt pressing member 13 to the belt release position when the door is opened and to the belt pressure contact position when the door is closed in conjunction with the door opening/closing, seat switch, and door switch. It is possible.

(Effect of the invention) As described above, the belt guide with belt stopper of the present invention is equipped with a guide roller that guides the belt, which is pulled out to the side of the seat from the retractor provided on the vehicle floor on the center side of the vehicle, in the vicinity of the side of the passenger's waist. The belt guide is provided with a stopper mechanism that presses the belt against the inner wall of the belt passage hole and limits movement in the longitudinal direction, and when the seat belt is worn, the belt pressing member is moved to the belt pressing position to wind the belt into the retractor. In addition to arbitrarily dissipating the force, when the belt is detached, the belt pressing member automatically returns to the release position by the spring force by simply pulling the belt a small length in the pull-out direction. When installed, the retractor's winding force does not act on the passenger restraint part of the belt.
It is possible to prevent the feeling of pressure on the occupant, which is a disadvantage of conventional seat belts with retractors, due to the belt retracting force on the occupant, with an extremely simple structure and easy operation. It is expected to have a significant effect on improving the belt-wearing rate due to comfort and, ultimately, ensuring the safety of passengers.

Furthermore, according to the present invention, when the belt is attached or detached, the belt that passes through the side of the occupant's waist is guided by the belt guide so that it does not come into contact with the occupant's clothing.
The movement in the longitudinal direction becomes smooth, and the action of the guide rollers also has the effect of preventing fuzzing of the belt surface caused by contact friction.
