Description

[Detailed explanation of the idea] The present invention relates to an improvement of a seat belt device.

Various seatbelts have traditionally been used as a measure to protect occupants in the event of a vehicle collision, but in recent years passive seatbelts have been used to automatically set the seatbelt to the seated or unfastened position relative to the occupant when the door is opened or closed. Seat belts are being developed.

The present invention was devised in view of the above, and consists of a first sill member attached to the sash at the upper rear of the door, a guide formed at the rear of the door and extending approximately vertically, and a slideable member attached to the guide. an interlocking device that moves the second slide member along the following guide above the lower part of the door when the door is closed and above when the door is opened; A seatbelt support member disposed on the body at or near the center of the vehicle, one end of which is fixed to the door or wound around the tractor, and the other end of which is inserted through the first through member, and the other end of which is attached to the seatbelt. A shoulder belt supported by the support member, and a waist belt fixed at one end to the door or wound around the tractor, passed through the second sled member, and having the other end supported by the seat belt support member. The interlocking mechanism includes a pinion that is pivotally attached to the door and that interlocks the second slide member via a cable, a rack that is slidably supported on the door and meshes with the pinion, and a rack that is slidably supported on the door and meshes with the pinion. a link connected to one end of the rack; a connecting rod having one end connected to the other end of the link and the other end pivoted to the vehicle body at a position displaced with respect to the rotation center axis of the door; and the door. Q between the fully closed position and the predetermined half open position.
At this time, guiding the connecting portion between the link and the connecting rod so as to maintain the link and the connecting rod in a mutually bent state,
a guide that prevents sliding displacement of the rack when the opening degree of the door exceeds the predetermined half-open position, and also allows the link to rotate about the connecting portion between the link and the rack. The seat belt device is characterized in that the second slit member is configured to be displaced to the upper end portion of the guide when the door is in the predetermined half-open position.

According to the present invention, the following effects are achieved.

(1) When the door is opened, the seat belt is pulled out from the retractor, and the seat belt is pulled out from the first sill member attached to the seat at the rear of the door and the seat located on the body at or near the center of the vehicle. The shoulder belt between the belt support members is stretched, and the waist belt between the seat belt support member and the second sled member that moves upward from the bottom of the door along the guide is stretched, and the seat belt is stretched. Both the shoulder belt and waist belt move away from the seat, making it easy for passengers to get on and off the vehicle.However, since the waist belt moves upward from the bottom of the door along the door-side edge or guide, the passenger's knees do not touch the waist belt. Never.

(11) Also, when the door is opened, the door-side end of the waist belt moves upward from the bottom of the door along the guide, and the door-side ends of the shoulder belt and waist belt approach each other. When riding, the position of the shoulder belt and waist belt can be confirmed at a glance at the same time, eliminating visual nuisance, and the position of both the shoulder belt and waist belt is almost the same, even though the occupant's body is relatively insensitive to the abdomen. Since it makes contact with the parts, it also eliminates tactile discomfort.

(Song) When the occupant sits on the seat and closes the door, the seat belt is unwound from both sides and rewound onto the tractor, and the shoulder belt is stretched between the first through member and the seat belt support member and placed above the occupant. The waist belt is stretched between the second sleel member, which has moved downward along the guide, and the seat belt support member, and fits around the waist of the occupant.

However, since the seat belt is fixed to the door, rewound to the tractor, or pulled out from the retractor, the seat belt may not fit around the occupant sitting in the seat when the door is opened or closed, or when it is separated from the occupant. There is no friction, so the occupant's clothes are not damaged, and the occupant does not feel uncomfortable due to the seat belt.

(■) Since the second sled member, which is one end of the waist belt used to open the door to the predetermined half-open position, is displaced to the upper end of the guide, it is not necessary to take the trouble to open the door to the fully open position. Even if the seat belt is not opened, the upper station waist belt is sufficiently far away from the body of the seated occupant so that the seated occupant can easily get on and off the seat, which is very useful when the door cannot be opened to the full open position, for example in a parking lot.

Hereinafter, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the schematic diagrams of this embodiment shown in FIGS. 1 and 2, reference numerals 2 and 2 show a vehicle body, 4 a seat, 6 a door pivoted to the vehicle body 2 so as to be openable and closable, and 8 an upper rear portion of the door 6. 10 is a first slew member attached to the satush 8,
12 is a guide formed at the rear of the door 2 and extends substantially vertically; 14 is a second sill member slidably attached to the guide 12; 16 is a guide that connects the second sill member 14 to the guide 12;
an interlocking mechanism for moving the door 6 along the lower part of the door when it is closed and to the center of the door when the door 6 is opened;
20 is a retractor with an emergency link device attached to the door; 22 is a retractor with an emergency link device attached to the door; 1 through member 10
, the third through member 18 and the second through member 14 are inserted through each through member 10, 18 and 14 in this order, and the other end is wound around the 1,11-rack 20 coaxially with the above one end. The seat belt includes a first slide member 10 and a third seat belt.
A shoulder belt 24 is constructed between the two sleeve members 18, and a waist belt 26 is constructed between the second sleeve member 14 and the third sleeve member 18.

The above configuration provides the following effects.

([) When the door 6 is opened as shown in FIG. The waist belt 26 is stretched between the guides 1 and 18.
2 to the center of the door.
Since both belts 24 and 26 are separated from the seat 4, the occupant can easily get on and off the seat, and the waist belt 26
Since the door side end of the vehicle is also located at the center of the door, the occupant's knees do not hit the waist belt 26.

(11) Also, when the door 6 is opened, the waist belt 26
The door side ends of the shoulder belts 24 and the waist belts 26 are located in the center of the door (this causes the door side ends of the shoulder belts 24 and the waist belts 26 to approach each other, so that the occupant gets on the vehicle (at this time, the shoulder belts 24 and waist belts 26
6 can be checked at a glance at the same time, eliminating visual nuisance, and the shoulder belt 24 and waist belt 26 can be checked at a glance.
Since both touch the rear part of the passenger's body, where the senses are relatively dull, it also eliminates tactile discomfort.

(iii) As shown in FIG. 2, when the occupant sits on the seat 4 and closes the door 6, the shoulder belt 24 and the waist belt 26 are wound back onto the tractor 20, and the shoulder belt 24 is
The waist belt 26 is stretched between the slew member 10 and the third slew member 18 to fit the upper body of the occupant, and the waist belt 26 is attached to the second slew member 14 that has been moved to the lower part of the door along the guide 12.
and the third slew member 18 to fit around the passenger's waist.

However, since both the shoulder belt 24 and the waist belt 26 have one end supported by the same third slide member 18 and the other end supported by the rear part of the quad door, the shoulder belt 24 changes when the door 6 is opened and closed. The difference between the amount of displacement of the waist belt 26 and the amount of displacement of the waist belt 26 is extremely small.
Further, since both the shoulder belt 24 and the waist belt 26 are fixed to the door 6, rewinded to the tractor 20, or pulled out from the retractor 20, the shoulder belt 24 and the waist belt 26 are attached to the seat by opening and closing the door 6. To prevent friction from being caused to the occupant when fitting the seated occupant or separating from the occupant, thereby preventing the occupant's clothes from being damaged and the occupant from feeling uncomfortable due to the belt.

Next, an example of the interlocking mechanism 16 and the guide 12 is shown in the third to sixth sections.
This will be explained according to the diagram.

30 is a bracket fixed to the vehicle body 2, 32 is a connecting rod whose one end is connected to the bracket 30, and 34
36 is a link whose one end is connected to the other end of the connecting rod 32; 36 is a rack whose one end is connected to the other end of the link 34 and is slidably attached to the door 6 only in the longitudinal direction; 38 is a rack A gear 40 is fixed coaxially with the gear 38 and has a larger diameter than the gear 38, and 42 is a gear that meshes with the rack 36 and is pivotally attached to the door 6. A gear 44 is coaxially fixed to the door 6 and has a smaller diameter than the gear 40, a cable engagement gear 46 is a cable engagement gear fixed coaxially with the gear 42 and has a larger diameter than the gear 40. 48 is an outer cable connected to the casing 46; 50 is a thin wire inserted around the outer cable 48 and the casing 46 and engaged with the gear 44; This is an inner cable that is spirally wound.

The guide 12 is configured by extending the outer cable 48 and disposing it so as to extend substantially vertically at the rear of the door 6, forming a slit toward the single room, and is attached to the inner cable 50 via a bracket 52. The second through member 14 moves due to the displacement of the inner cable 50.

Also, by opening the door 6, the connecting rod 32
The connection point between the bracket 30 and the connecting rod 32 is located inside or behind the vehicle, for example, with respect to the center of rotation of the hinges 54 and 56 that support the door 6 so as to be able to open and close the vehicle body 2c. .

Further, when the door 6 is opened and the rod 32 is pulled out from the door, the link 34 and the rod 32 are connected when the door 6 is between the fully closed position and the predetermined half-open position. When the degree of opening of the door 6 exceeds the predetermined half-open position, sliding displacement of the rack 36 is prevented, and the link 34 and the rack 36 are held in a mutually bent state. A guide 58 is fixed to allow the link 34 to rotate around the connecting portion of the door 6, and when the opening degree of the door 6 is at the predetermined half-open position,
4 is configured to be displaced to the upper end of the guide 12.

With the above configuration, the fourth effect described below can be obtained.

(Vl) By opening the door 6 to the predetermined half-open position, the second sleeve member 1, which is one end of the waist belt 26, is opened.
4 is displaced to the upper end of the guide 12, the waist belt 26 is sufficiently far away from the body of the seated occupant so that the seated occupant can easily get in and out of the vehicle, for example, without having to take the trouble to open the door 6 to the fully open position. This is very useful when the door 6 cannot be opened all the way in a car garage or the like.

Therefore, when the door 6 is opened by a predetermined amount, the rod 32 is pulled out, and accordingly, the rank 36 is pulled out by 9, and when the connecting portion with the link 34 comes into contact with the first cam surface of the cam 58 (this Gear 38 rotates, gear 40 and gear 42
The cable retaining gear 44 rotates through the cable retaining gear 44, the inner cable 48 is fed out, and the second through member 14 is connected to the guide 1.
2, and when the door 6 is opened further, the link 34 simply rotates around the connection point with the rack 36, and the rack 36 does not move, and the slide member 14 moves to the guide 1.
2, the uppermost position can be maintained.

Next, the retractor 20 will be explained according to FIGS. 7 to 11.

59 is a case with a U-shaped cross section, and 60 is a belt winding shaft rotatably attached to the case 59, which is always rotated in the winding direction with the shoulder belt 24 and waist belt 26 overlapped by a spring. energized.

62 and 64 are the same winding shafts (fixed ranaettes,
66 is a link attached to the case 59 so that it can slide only in the vertical direction in the figure, and 68 is attached to a hole 61 formed in the case 59 so that it can rotate only by a predetermined angle, and its tip is attached to the link 66. The pawl 70 is a pendulum which is inserted through the hole 67 formed.
When this G acts, it tilts and pushes up the link 66,
The link 66 is further pulled up when the claw 72 engages with the ranaette 62 which rotates when the seat belt is pulled out.
The pawl 68 rotates to the right and engages with the runaette 64, and is also locked in the hole 61 to restrict rotation of the winding shaft 60.
The seat belt is configured to be locked.

However, with only the above configuration, when an attempt is made to forcefully open the door 6, the pendulum 70 tilts, similar to the problem described above. When the door 6 is closed, it is activated only when the door is closed.
A pin 74 is provided that urges the link 66 downward when it is in the low position.

The pin 74 is fixed to the case 59 or slidably attached to the retainer 76, and is always urged downward by a spring 78, so that when the door 6 is opened, the rear end becomes the link 66.
When the door 6 is closed, its tip abuts against the contact member 82 fixed to the vehicle body side sill 80 below the door 6 and is pushed up. It is constructed so as not to interfere with the operation of the

In addition, if the retractor 20 cannot be attached to the lower end of the door 6 due to space constraints (if this is not provided, or if the retractor 20 cannot be attached to the rack 20 so that the pin 74 can come into contact with the contact piece 82 of the side sill 80), , link 66 of pin γ4
It can be divided into an engaging part for the side sill 80 or an abutting part for the pillar (not shown), and the engaging part and the abutting part can be configured to be interlocked by an operation link or a cable.

Note that the retractor 20 has a shoulder belt 24 and a waist belt 2.
6 are wound coaxially in a double layered state, and the device can be made very compact. A tractor may be used, and the seatbelt locking mechanism is not limited to the G-sensor type described above, but it goes without saying that a type that locks by sensing sudden belt withdrawal may also be used. .

The satush 8 to which the first slide member 10 is attached is manufactured to withstand the inertial energy of the occupant when the occupant is strongly thrown forward from the seat 4 and the shoulder belt 24 is strongly pulled in the event of a vehicle collision. If it is necessary to do so, and if it is not possible to manufacture it in this way, the first sliding member 10 or the surrounding part 8 can be used as a strength member such as a vehicle body pillar that is behind the door 6 when the shoulder belt 24 is strongly pulled. It must be configured to engage with the

An example of this will be explained with reference to FIG.
A first through member 10 is fixed to the flange 84 with a screw 86, and a striker 88 is formed at the rear end of the first through member 10.

A recess 92 into which the striker 88 enters is formed in the vehicle body pillar 90 behind the door 6, and a reinforcing member 94 is fixed to the back side of the recess 92, so that the first slew member 10 is secured in the event of a vehicle collision. When the sash 8 or the attachment portion to the sash 8 is deformed by being strongly pulled forward by the shoulder belt 24, the striker 88 engages with the recess 92 to prevent the slide member 10 from moving further forward. It is configured.

Further, it is preferable that the first slide member 10 can be moved up and down by an appropriate amount so that the shoulder belt 24 does not cause a hanging phenomenon for a small passenger. explain.

Note that parts that are substantially the same as those in the above embodiment are given the same reference numerals as above, and description thereof will be omitted.

The embodiment shown in FIGS. 13 and 14 is similar to Satsushi 8!
A first guide plate 96 having knurls formed on its surface and a second guide plate 98 formed to have a predetermined distance from the first guide plate 96 are connected to the screw 100 (
The first through member 10 is located between the two guide plates 96 and 98, and has a knurling formed on its contact surface with the first guide plate 96, and a striker at its rear end. 88 is formed, and a spring 102 with one end fixed by a rivet 104 is installed between the second guide plate 98 and the first slew member 10 is located on the left side in the drawing. is always biased so that its own knurling engages and is fixed with the knurling of the first guide plate 98, and when adjusting the height of the first slew member 10, the first slew member 10 is Push the member 10 to the right in the drawing against the spring 102 and move it upward or downward while keeping the knurling disengaged (if you move it and release your hand, the knurling will be engaged in that position by the spring 102). , the first through member 10 is configured to be fixed again.

Further, an anchor 106 is fixed to the pillar 90 along with a reinforcing member 110 by screws 108 over the entire moving range of the striker 88 of the first slew member 10, and the first slew member 10 is secured to the pillar 90 by the shoulder belt 24 in the event of a vehicle collision. The striker 88 is configured to engage the anchor 106 to prevent the sling member 10 from moving further forward when the sling 8 or the attachment portion to the sling 8 is deformed due to being strongly pulled forward. ing.

Note that instead of the spring 102, a spring member 116 consisting of a cylindrical fitting part 112 and a spring part 114 integrally formed of synthetic resin is inserted into the first slide as shown in FIGS. 15 and 16. It may be attached to the member 10, and if the knurling 118 is formed on the fitting portion 112, the cost can be extremely reduced compared to forming the knurling directly on the first through member.

In another embodiment shown in FIGS. 17 and 18, a first guide plate 122 and a second guide plate 124 each have a flange 121 extending toward the rear of the vehicle and having a plurality of retaining portions 120 formed on the sash 8. is fixed by a screw 126, the first slide member 10 is located between the guide plates 122 and 124, and a lock pin 128 that engages with the engaging portion 120 of the first guide plate 122 is fixed. , a striker 88 is formed at the rear, and a spring 132 whose center portion is fixed by a rivet 130 is compressed between the second guide plates 124, and the first slew member 10 is shown in the drawing. The lock pin 128 is configured to be constantly biased to the left and fixed by engaging with the engaging portion 120 of the first guide plate 122, and also adjusts the height of the first slide member 10. In this case, push the slide member 10 to the right in the drawing against the spring 132, move the lock pin 128 upward or downward with it removed from the engagement part 120, and release your hand, and the spring 132 will release the lock pin. 12

The pillar 90 also has an anchor 106 and reinforcing material 110 that are exactly the same as those shown in FIGS. 13 and 14 above.
is installed and its operation is the same, so its explanation will be omitted.

Also in this embodiment, instead of the spring 132, a spring member 1 as shown in FIGS. 15 and 16 is used.
16 can be used, in which case the same spring member 1
Of course, it is not necessary to form the 16I knurl 118.

Another embodiment shown in FIGS. 19 and 20 includes a flat first guide plate 134 on the sash 8 and a second guide plate 138 having a flange 136 extending forward.
is fixed by a screw 139g, and the first slide member 10
is located between the two guide plates 134 and 138, and has a striker 88 formed at its rear end, and a clip 140 having an M-shaped cross section so as to sandwich the flange 136 of the second guide plate 138 is attached by a rivet 142. When the height of the first sled member 10 is adjusted, the first sled member 10 is attached to one end of the clip 140. Push the lever 144 and release the same clip 1.
If the clip 140 is released from the flange 136 of the clip 140 and moved upward or downward and released the grip, the clip 140 is released.
It is configured so that it can be fixed again.

The pillar 90 also has an anchor 10 which is exactly the same as that shown in FIGS. 13, 14, 17 and 18 above.
6 and a reinforcing member 110 are attached, and their operations are the same, so their explanation will be omitted.

It goes without saying that the striker 88 shown in FIGS. 12 to 20 is constructed so as not to interfere with the recess 92 of the pillar 90 or the anchor 106 when the door 6 is opened or closed.

Further, instead of the anchor 106, a recess 92 as shown in FIG. 12 may be formed in the pillar 90 so as to have at least the same length as the anchor 106.

The third slide member 18 is not limited to the one fixed to the seat 4f via the bracket 17 as shown in FIG. It may be fixed to

Further, if the belt 22 is configured to be detachable from the third through member 18 as shown in FIG. 21, the seat belt device of the present invention can be used as a non-passive seat belt.

Referring to FIG. 21, the through member 18 is connected to the main body 1.
46, the same main body 146 (mounting bracket 1 formed here)
48, the main body 146 (one end is pivotally supported, the other end is a shaft 150 that can be freely engaged and detached, and the operation button 152), and when used as a passive seat belt, insert the shaft 150 & the seat belt 22, and connect the same shaft 150 to the main body. 146f may be attached, and in that case, the operation button 152 functions as a button for dropping the belt in an emergency.

In addition, when using it as a non-passive seat belt, after the occupant sits on the seat 4, when it is necessary to fasten the seat belt 22, the passenger holds a part of the seat belt 22 and fastens the third through member 18t. When it is not necessary, the seat belt 22 can be removed from the seat belt member 18 by operating the operation button 152.

In the case of the above example (also in this case), when the seatbelt 22 is removed and the slide member 18 is removed, the seatbelt 22
The belt is stretched vertically between the first slew member 10 and the second slew member 14 (along the rear edge of the door 6).
However, since there are no metal fittings in the middle of the stretched belt, there is no possibility of collision with the door 6 or the door glass. It is possible to prevent the generation of noise.

In addition, as shown in FIG. 22, the third through member 18 is
Of course, the tongue 154 through which the seat belt 22 is inserted, and the buckle 156 fixed to the seat 4 or the floor, which can be freely engaged and disengaged, may also be used.

Further, as shown in detail in FIG. 23, this embodiment (in this case, the handle 158 is attached above the upper end of the guide 12 that extends over the inner surface of the door 6 (in the forward direction of the vehicle). ing.

This handle 158 is attached to the door 6 as shown in FIG.
When the occupant is seated and tries to close the door 6 with the door 6 open (if the occupant is seated and his/her arm is under the waist belt 26), the door 6 closes. The second slide member 14 is the door side end of the belt 26
This was installed in order to eliminate the problem of the waist belt 26 getting tangled around the arm and having to fix the hand that was attached to the door 6.
When closing the door, put your arm between the waist belt 26 and the shoulder belt 24 and hang the handle 158 (handle 158) to close the door, so the waist belt 26 will not get tangled around your arm.

In addition, when getting into the vehicle, first place your hand on the rear end of the handle 158, slide it, and then sit on the seat 4 and close the door 6 while keeping your hand on the front end of the handle 158. I can do this.

Note that when opening door 6 from a seated position, handle 1
58 (If you rub your hand to open the door 6, the door side end of the waist belt 26 will rise (this will prevent the waist belt from getting tangled around your arm.

In the above-mentioned actual case, the shoulder belt 24 and the waist belt 26 were constructed from one seat belt 22, but as shown in FIG. The support member 159 may be attached as shown in FIG.
0 and the tongue 160 removably engage (
Seat 4 or floor (fixed buckle 16)
It may be composed of 2.

In addition, the support member 159 is divided into two parts (the shoulder belt 24
It is also possible to attach the waist belt 26 to the other side.

In this case, the shoulder belt 24 and the waist belt 26 are formed separately, or the tongue 154 shown in FIG. 19 is fixedly attached by applying friction against the seat belt 22f (not shown). (The tongue 154 shown in FIG. 22 is movable with respect to the seat belt 22f.)

) If the shoulder belt 24 and waist belt 26 are wound coaxially as shown in Figs. belts 24 and 26 should be wound on separate glue tractors or retractors with separate shafts (as they no longer perform this function).
It is necessary to configure this so that it can be wound up.

An example of this will be explained with reference to FIG. 26, but portions that are substantially the same as those in FIGS. 7 to 11 are given the same reference numerals and detailed explanations will be omitted.

The retractor 164 is installed in a case 59 having a U-shaped cross section (in which two winding shafts 60 and two ratchets 62 and 64 are provided, respectively), the upper winding shaft 60 (the shoulder belt 24 is mounted on the lower winding shaft 60), and the lower winding shaft 60 is The waist belt 26 is wound up, and each ratchet 62 (a link 66 having two engageable pawls 72 is disposed, and a hole 67t of the link 66, which can further engage the respective ratchet 64) is disposed. The tip of the pawl 68 is inserted, and the link 66 and the pawl 68 are operated by the pendulum 70 in the same way as the retractor 20 shown in FIGS.
