DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a passive seat belt device that is capable of automatically attaching restraining webbing to an occupant after the occupant is seated.

[Conventional technology]

Although occupant restraint webbing is extremely safe as it restrains and protects occupants in the event of a vehicle emergency, its installation rate is extremely low due to the complexity of installing it and the feeling of pressure while wearing it. There is.

For this reason, various passive seat belt devices have been proposed in the past that can automatically attach webbing to an occupant after the occupant is seated.

In particular, a guide rail is provided on the roof side member of the vehicle in the longitudinal direction of the vehicle, the outer end of the webbing is attached to a bogie that moves guided by the guide rail, and the driving force of the motor is connected to the bogie. The passive seatbelt device, which moves the dolly in the longitudinal direction of the vehicle to bring the webbing into contact with and separate from the passenger seat, automatically attaches and releases the webbing to the occupant seated in the notebook, has been highly praised for its reliability. ing.

[Problem that the invention seeks to solve]

However, in this passive seat belt device, it is necessary to provide a dolly, a guide rail that guides the dolly, a transmission member that transmits the driving force of the motor to the dolly, etc. on the roof side of the vehicle, so these parts protrude into the vehicle interior. It was a book that made the interior space smaller. Furthermore, if the single-chamber side of the truck is covered with a covering material, the truck itself becomes heavy, and there is a problem in that the seatbelt cannot be smoothly attached or removed.

In consideration of the above facts, the present invention has been developed so that when the webbing automatic device is operated to release the webbing, the part of the dolly or anchor to which the webbing is attached and which is moved in the longitudinal direction of the vehicle does not interfere with the head of the riding ridge, and the part of the dolly or anchor is always mounted on the dolly. The purpose of the present invention is to provide a passive seat belt device that guarantees smooth running of the vehicle.

[Means for solving problems]

The passive seatbelt device of the present invention has a seatbelt attachment part and a sliding part, and the seatbelt attachment part includes a slider to which one end of the seatbelt is fixed for selectively restraining or unrestraining an occupant. , a flexible driving force transmission member that engages with the slider and transmits the driving force, an interior material disposed on the side of the ceiling of the single room, and a sliding portion of the slider that slides in the longitudinal direction of the vehicle. The slider has a sliding groove for movably storing and an interior material abutting part, and also includes a guide means interposed between the roof side member and the interior material, so that the guide means can move between the roof side member and the interior material. The interior material is kept separated for a predetermined period of time, and a slit is formed between the lower end of the interior material and the roof side member, and a seat belt fixed to the slider moves in the longitudinal direction of the vehicle through the slit. It is arranged so that it is possible.

[Effect]

According to the above configuration, the single room side of the guide means is covered with the roof lining, which is an interior material, and the roof lining is fixed to the roof lining support part of the guide means, so that the roof lining and the roof side member The width of the slider running space (slit) formed between the slider and the slider is kept constant. Therefore, since the sliding portion of the slider is completely covered and protected by the roof lining, there is no interference with the occupant's head when the slider is operated, and the slider can always be operated smoothly.

〔Example〕

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

In the embodiment shown in FIGS. 1 and 2, the occupant restraining webbing 10 is passed through a winding device 14 that winds up the webbing by the force of the inner end 12 of the webbing 10 on the vehicle floor.
It is locked to 5. This winding device 14 is attached to a substantially central portion of the vehicle in the left-right direction. This inner end 12
It is also possible to directly lock onto the floor portion 15 without using the winding device 14.

On the other hand, the outer end 16 of the webbing 10 is attached to a truck 18 as a slider so as to be moved in the longitudinal direction of the vehicle along the roof side member 20 of the vehicle. This movement brings the webbing 10 into contact with and away from the passenger seat 22, so that the passenger seated on the seat 22 can automatically attach and release the webbing 10.

As shown in FIGS. 3 and 4, the bogie 18 is provided with a movable plate 24 as a sliding part, and a seatbelt attachment part which is a part of the anchor of the movable plate 24 protrudes toward the vehicle floor. An elongated hole 28 is bored in the extension 26 of the webbing 10 to lock the outer end 16 of the webbing 10. Further, four shafts 30 are fixed to the moving plate 24 in parallel with each other, and these shafts 30
As shown in FIG. 4, a drum-shaped wheel 32 with a reduced diameter at the center is pivotally supported on each of the wheels.

As shown in FIG. 4, this wheel 32 is held between a guide rail 34 having a U-shaped cross section and is rotatably movable in the longitudinal direction of the guide rail 34, that is, in the longitudinal direction of the vehicle.

More specifically, since the guide rail 34 has a U-shaped cross section as described above, the slider sliding groove 35 is formed in the U-shape, and the slider sliding groove 35, especially the relative orientation of the groove 35, is formed in the U-shape. The wheels 32 are removably guided by the edges. In this embodiment, a truck with wheels is used as the slider, but the present invention is not limited to this, and it goes without saying that, for example, a sliding member without wheels may be used as the slider.

The guide rail 34 has a U-shaped cross section and its center portion is fixed to the inside of the roof side member 20 by a plurality of mounting screws 36, and the guide rail 34 is arranged so that the opening faces toward the inside of the car.

A flange piece 38 is still extended to the upper part of the guide rail 34, and is fixed to the 7-rank piece 42 extended to the upper part of the slide rail 40 by a mounting screw 44, so that the slide rail 4゛0゜ guide rail 34 and arranged in parallel.

The slide rail 40 has a 7-rank piece 42.
A flange piece 72 as a roof headlining support portion is provided substantially parallel to the flange piece 72 . The guide rail 34 and slide rail 40 constitute a guide means. A rectangular groove 46 is continuously formed between the seven flange pieces 42 and 72 of the slide rail 40 along the longitudinal direction, and from the intermediate depth portion of the rectangular groove 46, the groove of the rectangular groove 46 is formed. A slide groove 48 as a groove for a driving force transmitting member whose width is substantially increased is bored in the slide groove 48, and a thick tape 50 as a flexible driving force transmitting member shown in FIG. is housed therein so as to be slidable in the longitudinal direction of the slide rail 40.

In this embodiment, the guide rail 34 and the slide rail 40 are separate bodies, but the present invention does not need to be limited to this. For example, the guide rail 34 and the slide rail 40 are separate bodies.
It is also possible to adopt a guide means in which the two are integrated. Further, although the 7-rank piece 72 is extended from the slide rail 40, the present invention is not limited to this, and for example, a structure in which the 7-rank piece 72 is extended from the slide rail 40 may also be adopted.

As shown in FIG. 5, this thick tape 50 has a rectangular cross section perpendicular to the longitudinal direction, and has a large number of openings 51 formed at equal intervals along the longitudinal direction. In addition, the dimensions of the rectangular portions of this thick tape 50 are the same as those of the slide rail 4.
By being inserted into the slide groove 48 of 0 with a slight gap, not only tensile force but also compressive force can be transmitted. Moreover, it is preferable to use synthetic resin as the material of this tape 50, and its appropriate flexibility allows it to be bent with a small curvature.

A sliding block 54 is fixed to one end of this thick tape 50 by four rivets 52. The protrusion 56 protruding from the sliding block 54 in the direction of the sliding block 24 is formed with a recess 59 for accommodating the protrusion 58 protruding from the movable plate 24 in the direction of the sliding block 54, and the protrusion 58 is inserted into the recess 59. By doing so, when the sliding block 54 moves in the longitudinal direction of the vehicle together with the thick tape 50, the trolley 18 can be simultaneously moved in the longitudinal direction of the vehicle.

An elongated hole 60 is bored at the end of the movable plate 24 on the rear side of the vehicle, and one end of a narrow webbing 62 is locked therein. The other end of the narrow webbing 62 is wound onto a winding shaft 68 of a winding device 66 which is fixed to the roof side member 20 by a mounting bolt 64 behind the guide rail 34 of the vehicle.

This winding device 66 has the same structure as the winding device 14 that winds up the inner end portion 12, and is a winding device using a known emergency mechanism that suddenly stops unwinding the webbing 62 only in case of a vehicle emergency. It is a locking retractor, and normally winds up the webbing 62 with the biasing force of a mainspring spring 70. Therefore, the movable plate 24, which is connected to the winding device 66 via the webbing 62, is moved toward the rear of the vehicle by the biasing force of the mainspring spring 70, and in the event of a vehicle emergency, the winding device 66 stops unwinding the webbing. The outer end 16 of the occupant restraint webbing 10 can be prevented from being pulled out toward the front of the vehicle.

As shown in FIG. 4, from the slide rail 40, a seven-rank piece 72 extends in the opposite direction to the flange piece 42, that is, toward the floor of the vehicle, and serves as an abutting part for the roof lining 74. The roof lining 74, which is the ceiling lining inside the vehicle, is attached to the piece 72 with the mounting screws 7.
It is locked by 5. Therefore roof lining 74
A guide rail 34 is installed between the roof side member 20 and the roof side member 20.
, the slide rail 40, the truck 18, etc. are sandwiched, and a running space (slit) for the slider is formed between the lower end 74A of the roof lining 74 and the roof side member 20, and the guide rail is inserted into the vehicle interior. 34,
The slide rail 40 and the truck 18 are not exposed. In addition,
In this embodiment, the roof lining 34 is brought into contact with the flange piece 72 as an interior material, but the present invention does not need to be limited to this. Interior materials may be used. In particular, since the tape 50, which is a driving member of the cart 18, can transmit compressive force as well as tensile force, the slide rail 40 simply has a groove 46.0 that accommodates the tape 50.
48 is sufficient, the outer diameter is small, and the distance between the roof side member 20 and the roof second innings 74 can be significantly reduced. On the other hand, conventional seatbelt devices that drive the webbing using wires that transmit only tensile force require two wires between the roof side member and the roof lining to drive the bogie toward the front and rear of the vehicle, respectively. In addition, it is necessary to accommodate a pulley to guide the ends of these wires, a guide pulley to bend the trajectory of the wire, and a tension adjustment device to maintain the tension of the wire within a predetermined range. bulged out into the cabin, reducing the passenger living space inside the cabin.

Note that the guide rail 34 and slide rail 40 are preferably made of aluminum material.

Further, at the front end of the guide rail 34, as shown in FIGS. 6 and 7, a forward tilting type stopper 76 is fixed by a mounting bracket 7, and one side of the stopper 76 projects into the guide rail 34. Therefore, this forward tilting type stopper 76 can restrict the movement to t' when the moving plate 24 is moved by the maximum amount toward the front of the vehicle, as shown by the two-dot chain line in FIG.

In addition, as shown in FIGS. 3 and 8, the guide rail 3
A backward type stopper 78 is fixed to the slide rail 40 near the rear end of the vehicle No. 4 with a mounting screw 77.
Its negative side protrudes into the rectangular groove 46 of the slide rail 40. Therefore, this backward-looking stopper 78 is adapted to restrict the amount of backward movement of the thick tape 50 within the slide groove 48, as shown in FIG.

As shown in FIGS. 9 and 10, the slide rail 40 is attached to the inside of the passenger compartment of the vehicle's 70 door tilter 79 with a screw 44.
and descends along this front pillar 79. The lower end of this slide rail 40 is the first
As shown in FIG. 1, it is attached to a sprocket housing 82.

This sprocket housing 82 is shown in FIGS.
As shown in the figure, it is formed into a particularly thick disk shape, and there is a recess 86 for accommodating the Sugerocket foil 84 inside it.
The sprocket housing 82 is formed into a substantially circular shape, and the accommodation recess 86 is closed when the sprocket housing 82 and the lid member 88 are fixed.

Here, the sprocket housing 82 and the lid member 88 have an arcuate groove 9 near the periphery of the housing recess 86, which has a smaller diameter than the outer diameter of the housing recess 86 but is deeper than the housing recess 86.
0 is formed and the sprocket foil 8 of the thick tape 50
It is designed to mesh with 4 and accommodate soundly. Although this arcuate groove is annular, it does not necessarily have to be connected in an annular manner. Further, a pair of tape insertion grooves 92 and 94 extending substantially tangentially are provided in the arcuate groove 90.
They are formed to have the same depth as the sprocket wheel 84, and are oriented in opposite directions to each other for insertion and removal of the thick tape 50 that engages with the sprocket foil 84.

Therefore, the thick tape 50 enters into the arcuate groove 90 through the tape insertion groove 92, and after engaging with the sprocket wheel 84, passes through the entire tape insertion groove 94 and exits to the outside of the sprocket housing 82.

Here, the sprocket housing 82 and the lid member 88 have preliminary insertion grooves 96° 98.100, 1 that contact the arcuate groove 90 of the housing recess 86 similarly to the tape insertion grooves 92 and 94.
02 is formed and the thick tape 50 is bent by the sprocket housing 82 (angle θ in FIG. 16) 1
! -Can be changed.

Also, this sprocket housing 82 has three mounting flanges 104 protruding from the outer periphery at equal intervals.By applying the mounting flanges 106tl- to the front of the vehicle via a bracket 107 as shown in FIG. Pillar 7
A sprocket housing 82 is fixed to the sprocket housing 9.

Therefore, this sprocket housing 82 can be assembled after wrapping the thick tape 50 around the sprocket foil 84, thereby making it possible to significantly improve work efficiency. The relative position of the thick tape and the sprocket wheel 84 during assembly is as shown in FIG. All you have to do is wrap it around, and positioning is extremely easy.

Additionally, six thick support protrusions 108 having the same shape as the mounting 7 flange portion 104 are fixed to the outer periphery of the sprocket housing 82, and these support protrusions 108 extend from the end of the slide rail 40. Mounting piece 11
0 is screwed on. Therefore, this support protrusion 1
08 is thick tape 50 to sprocket housing 82
When changing the insertion position and removal position of the support projection 108, one of the support projections 108 corresponding to the preliminary insertion grooves 96 to 102 is selected.

The front sprocket wheel 84 has a center hole 1 of the lid member 88.
A drive shaft 114 of a reversible motor 112 that passes through the sprocket 11 and is inserted into the sprocket nozzle 82 is fixed. This motor 112 is inserted into the front pillar 79 through a notch 116 formed in the front pillar 79, and is fixed inside the front pillar 79 with a bracket 118 and mounting screws 120. The other motor is connected to a vehicle power supply (not shown) and driven, but this drive is driven by the opening/closing of the entrance/exit door (not shown) and the seat switch (not shown), which is embedded in the passenger seat and detects when the passenger is seated. It is designed to be started by the operation of .

Here, the direction of rotation of the motor is such that when the occupant opens the door when getting on or off the vehicle, the sprocket wheel 84 is rotated counterclockwise as shown in FIG. 1.13, and clockwise when the door is closed. The number of rotations increases before the truck 18 comes into contact with the forward-sloping stopper 76 at the front end of the guide rail 34, and before the truck 18 moves toward the rear of the vehicle, the thick tape 50 tilts backwards as shown in FIG. It is designed to stop before contacting the mold stopper 78.

A second slide rail 122 is fixed to the sprocket housing 82 by a mounting screw 106 in the same manner as the slide rail 40, and this second slide rail 122 is connected from the lower end of the front pillar 79 as shown in FIG. An opening 125 into the vehicle's rocker panel 124 as shown.
When the sprocket wheel 84 is rotated counterclockwise in FIG. 1, the thick tape 50 is pushed out from the second slide rail 122 into the rocker panel 124.

The thick tape 50 has a length extending at least from the sprocket housing 82 to the movable truck 18 so that the drive of the sprocket wheel 84 is always transmitted to the truck 18.

Note that 15A in FIG. 9 is a front pillar garnish, 15B in FIG. 10 is a cowl side trim, and 15A is a front pillar garnish.
Reference numerals 15C and 15D in FIG. 7 indicate a carpet and a scuff plate, respectively.

To explain the operation of the first embodiment of the present invention configured as described above, FIG.
8 has been moved by the maximum amount to the rear end of the vehicle on the guide rail 34, and the occupant is now wearing the webbing. Since the webbing can be unwound from the winding device 14 in this webbing-attached state, the driving posture can be changed.

Furthermore, if the vehicle is in an emergency situation such as a collision, the inertia lock mechanism built into the winding device 14.66 suddenly stops unwinding the webbing 10 and the narrow webbing 62, so that the trolley 18 can reliably weave the webbing. 10 is prevented from being pulled out toward the front of the vehicle, the occupant is restrained, and safety is guaranteed.

Next, when the passenger exits the vehicle, open the door and motor 1 will be activated.
12 rotates the sprocket wheel 84 counterclockwise in FIG. 1, a tensile force acts on the thick tape 50, and the thick tape 50 is moved in the direction indicated by the arrow within the slide rail 40. As a result, the truck 18, which is locked via the sliding block 54, is moved forward of the vehicle along the guide rail 34, so that the webbing 18 is moved forward as shown by the two-dot chain line in FIG.
The outer end 16 of the 0 is moved largely toward the front of the vehicle.

Therefore, the webbing 10 forms a space for the passenger to get off the vehicle between the webbing 10 and the passenger seat 22, and the passenger can easily get off the vehicle.

Next, when the occupant re-enters the vehicle, if the occupant closes the door (not shown) after seating, the motor 112 is reversed and the thick tape 50 is rotated.
A compressive force is applied to it, and it is moved in the opposite direction to the direction of the arrow. Therefore, since the sliding block 54 moves in the direction of the winding device 66, the carriage 18 is also moved in the direction of the winding device 66, that is, toward the rear of the vehicle, with the biasing force of the mainspring spring 70 being applied to the carriage 18, as shown in FIG. The webbing can be automatically attached.

Further, in this embodiment, the lower end 7 of the roof lining 74
4A forms a narrow slit between the lower end portion 20A of the roof side member 20 and the extension portion 26 of the movable plate 24 in which only the extension portion 26 of the moving plate 24 can move in the longitudinal direction of the vehicle. Only the protruding moving plate 24 is visible, and the truck 18 and tape 50 moving in the longitudinal direction of the vehicle are not visible, so these do not move near the occupant's head and the occupant does not feel frightened. Furthermore, this slit continues along the lateral edge of the passenger compartment, that is, along the window glass, in the front and rear direction of the vehicle.
Since the extension part 26 of the moving plate 24 also moves in the longitudinal direction of the vehicle along the window glass, it passes through the farthest position from the occupant. In addition, since the slit faces toward the floor rather than toward the occupant's face, there is no interference with the occupant's head when the trolley 18 moves.

Next, FIG. 18 shows another embodiment of the means for locking the thick tape 50 and the movable plate 24. In FIG.

Here, the protrusion 56 of the sliding block 54 is a protrusion 58 protruding from the moving plate 24 in the direction of the thick tape 50.
A is contacted from the rear side of the vehicle, that is, from the winding device 66 side, allowing the two to separate. Therefore, when the sliding block 54 is moved to the front of the vehicle by the thick tape 50, the moving plate 24 is moved to the front of the vehicle via the protrusion 58A.
It is now possible to move to the front of the vehicle independently.

Accordingly, in this embodiment, even if the occupant changes his or her driving posture while the webbing 10 is being attached, the moving plate 24 moves toward the front of the vehicle while unwinding the narrow webbing 62, increasing the degree of freedom for the occupant. . Furthermore, if the occupant grasps the webbing 10 while moving the outer end 16 by driving the thick tape 50, or even if the occupant intentionally moves his/her body, the carriage 18 will move toward the sliding block 5.
6 and can be separated from each other to prevent damage to each part. The other configurations are the same as those of the previous embodiment, and the same effects can be obtained.

Next, in FIGS. 19 to 22, a wire 150 is used as a transmission member for transmitting the driving force of the motor 122 to the truck 18, which is different from the above embodiments.

This wire 150 is capable of transmitting compressive force as well as tensile force applied in the longitudinal direction, and one end is shown in FIG. 20.

As shown in FIG.

A worm wheel 160 is pivotally supported on this shaft 158 and meshes with a worm 162 that is pivotally supported on the base 154 . This worm 162 is driven by a motor 122 attached to a bracket roof side member 20 (not shown).

A pressure receiving disk 164 is rotatably supported on the shaft 158, and a compression coil spring 170 is interposed between the ring 166 and the ring 166 which is secured to the shaft 158 by a C-shaped tongue 166. Therefore, this pressure-receiving disk 164 is pressed against the worm foil 160 by the biasing force of the spring 170, and rotates together with the worm foil 160 due to the frictional force.

This pressure receiving disk 164 has an annular groove 17 with a U-shaped cross section.
A thin rotating plate 174 having a diameter of 2 is fixed. One side of a tapered winding drum 176 is fixed to the bottom of the annular groove 172 to form a wire accommodating portion 178 with a tapered cross section between it and the peripheral edge of the rotary plate 1740.

Here, a U-shaped wire guide wall 180 is formed in the pace 154, and the inside thereof is used as a wire guide groove 182, which is arranged in the tangential direction of the largest diameter part 178 of the annular wire housing part 178, and the wire guide wall 180 is disposed in the tangential direction of the largest diameter part 178 of the annular wire housing part 178. The housing portion 178 and the sliding groove 48A of the slide rail 40 are connected. Further, the end of the wire 150 is connected to the minimum diameter portion 178B of the winding drum 176.
It is fixed to.

Therefore, the winding drum 178 rotates the wire 1 by the rotation of the motor 112.
50 is gradually wound up from the smallest diameter portion to move the sliding block 54 toward the front of the vehicle, and by reversing the motor 122, the shear wire 150 is gradually unwound from the largest diameter portion, and the compressive force of the wire 150 causes the sliding block 54 to move toward the front of the vehicle.
is moved to the rear of the vehicle.

Note that the configuration other than the above is the same as that of the second embodiment,
The sliding block 54 is in contact with the projection 58A of the moving plate 24 from the rear side of the vehicle.

Also in this embodiment configured in this way, the slide rail 40, guide rail 34, etc. are connected to the roof side member 2.
0 and the Roux 7 lining 74, it is possible to obtain the same effects as in each of the embodiments described above.

〔Effect of the invention〕

As described above, according to the present invention, the interior material disposed toward the inside of the vehicle is fixed to the interior material abutting portion of the guide means, and the interior material is fixed between the lower end of the interior material and the /-7 side member. Since the slit opens substantially downward, the guide means and the sliding portion of the slider are not exposed to the single chamber side.
