Abstract

(57) [Summary] [Problem] To make a passenger's shoulder belt of a passenger car a barrier-free product for the elderly. SOLUTION: A resin grip 10 comprising a plate-shaped mounting portion 19 having a grip portion 11 is provided by retrofitting on a tongue 6 of a shoulder belt 2a suspended from an outlet of a center pillar. The thickness direction of the portion 19 is divided into two parts, the tongue 6 is temporarily placed on one of the mounting portions 19a, and the presence or absence of play is checked. If there is any play, the spacer 29 is packed, and then the tongue 6 is removed. Since the grip 10 is sandwiched between the mounting portions 19a and 19b, the grip 10 can be mounted on any of the commercially available belts without play, so that the elderly can use it with confidence.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt system for an elderly person riding a passenger car, and more specifically, a seat belt system in which a belt is handled in a barrier-free manner.
The present invention relates to a grip added to the Tobert system.

[0002]

2. Description of the Related Art Recently, for persons who are partially or wholly functionally impaired, such as elderly persons and persons with disabilities, and persons who cannot perform the same actions as healthy persons (healthy persons) such as children, I began to give special consideration.

That is, it is essential for a healthy society that elderly people and persons with disabilities be independent of their own lives and be actively involved in the society. Therefore, it is necessary to correctly grasp the handicapped state and to install equipment and tools. Elimination of inconvenience (barrier), that is, barrier free has been improved.

As one of the barrier frees, there is a method of compensating for the lowered ability because the physical function decreases as the age increases. For example, the barrier free in a passenger car is considered as follows.

[0005] For example, when getting on and off a vehicle, the lower limbs support the load to move the height of the center of gravity of the body. Therefore, the function of the nervous system for controlling the posture is deteriorated and the lower limb muscle strength is decreased (muscles due to aging Atrophied), causing difficulty in getting on and off.

[0006] Therefore, regarding the muscle load on the lower limbs when standing up from the seat, the elderly have a greater load on the lower limbs than the younger ones, but the use of a handrail reduces the load on the lower limbs and significantly reduces the muscle load. It is said to be.

Regarding the relationship between the operating force for opening and closing the door and the height at which it is easy to operate, comparing the younger age group (early 20's), the elderly (around 70's) and 80's, As it becomes, the allowable range of the height that is easy to operate becomes narrower, and the characteristics of the elderly who are difficult to adapt to the existing in-vehicle equipment will appear. That is, it is difficult for the elderly to reach their hands backward and upward.

On the other hand, a passenger car is obliged to be equipped with a seat belt and a seat belt attaching device for preventing the passenger from moving to the front of the seat when the automobile is impacted. .

The seat belt attachment device is also restricted to be provided at a position where it does not interfere with getting on and off the vehicle.

This seat belt generally has a two-point type, a three-point type and a four-point type, and the front seat has a three-point type.
Although the two-point type is used for the rear sheet, recently, the three-point type has also been used for the rear sheet.

Three-point type seat belts used for front seats and rear seats, particularly shoulder belts, are generally pulled out from an outlet provided at the upper and lower intermediate portions of the center pillar and the rear pillar, and are classified into vehicle types. Some of them are suspended through an anchor with an upper slip guide provided at the upper part of this take-out port, and a tongue plate slidably fitted is provided at the middle or tip of this belt.
The seat is designed to be inserted into and removed from the buckle that is integrated with the front and rear seats.

Therefore, the passenger riding on the front seat or the rear seat, after sitting, grips the tongue plate and pulls out the belt from the seat belt retractor against the winding force. After wearing the lap belt that restrains the waist and the shoulder belt that restrains the upper body,
Insert the buckle into the buckle.

By the way, there have been complaints regarding the comfort and convenience of the general seat belts that it is difficult to remove the belt, and it is difficult to insert or disengage the tongue plate from the buckle. Various solutions have been proposed.

For example, the following proposals have been made.

That is, regarding the seat belt for the driver (healthy person), in order to eliminate the difficulty of taking the seat belt because it is separated from the front seat, a finger hook or a finger-hanging piece on or near the tongue plate itself. It has been proposed to provide a grip and use this to easily pull out the seat belt (see Japanese Utility Model Publication No. 60-110056 and Japanese Utility Model Publication No. 2-38253).

By the way, when the proposal for such a healthy person is applied to a seat belt used by an elderly passenger, it has been found that the following problems occur.

[0017]

Since the finger-holding piece or the grip is intended for a driver who is a normal healthy person, even if the finger-hanging piece or the grip is downsized, it can be operated with one finger, but it is expensive. If an elderly person wants to operate this, it is difficult with one finger to extend the hand backward and / or upward, which is difficult for the elderly and the belt is difficult to handle.

Originally, there are many elderly people who do not bend their fingers well, those whose elbow joints do not move easily, those who have weakened grip, and those who have very weak hands and fingers. For a person, such a finger hanging piece or grip is not preferable as a barrier-free article.

In particular, the above-mentioned Japanese Utility Model Publication No. 60-110056.
In the publication, in the case of avoiding the belt mounting type finger hanging piece which lowers the belt strength and providing the finger hanging piece on the tongue plate to facilitate the pulling out of the seat belt, in FIG. There is a proposal that the belt insertion plate is covered with a soft synthetic resin cover and a finger hook is integrally projected on this cover.However, since the belt insertion plate is covered with the soft cover, it is already attached to the vehicle body. It is difficult to add a finger hook piece to the tongue plate, it is a replacement of the entire belt system, and the cost is high, therefore, it is not a custom-made item but an off-the-shelf item with an auxiliary component effectively used, In other words, it cannot be adopted because it does not fit the idea that an elderly person can act as a barrier-free item or a welfare tool of a small size to perform an independent action.

Therefore, the present invention solves such a problem,
The main purpose is to provide a seat belt barrier-free article that is suitable for elderly people, and a highly flexible grip is attached to a metal tongue plate fitted with a flexible seat belt to prevent looseness. The secondary purpose is to eliminate the anxiety of elderly people who use it without suddenly changing it due to blurring.

[0021]

In order to achieve the above object, the gist of the present invention is as follows: 1) A shoulder belt provided on a seat of a passenger car is an outlet at an upper portion or an upper and lower intermediate portion of a pillar. An existing seat belt system in which a tongue plate is mounted on the shoulder belt, and the tongue plate has a plate-shaped mounting portion in which a flexible grip portion is integrated. In order to attach the resin grip by retrofitting, the attachment portion is divided into two in the thickness direction, the tongue plate is placed on one of the attachment portions, and the presence or absence of backlash is checked. It is a grip added to the seat belt system for passenger cars, which is characterized by holding the tongue plate as it is without rattling, and 2) Spacers are replaceably packed in the inside of the mounting part and commercially available. Noi Together also adapted for bets, the grip elderly barrier-free - - Les Tangupure of a grip to be added to safety belt systems - passenger car sheet according to claim 1 in which the article.

[0022]

The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

FIG. 1 is an overall perspective view of an embodiment of the present invention, FIG.
1 is an exploded perspective view of an essential part of FIG. 1, FIGS. 3 and 4 are explanatory views of a mounting method, and FIG. 5 is an enlarged detailed view of an essential part of FIG.

The seat belt system of this embodiment is convenient for a three-point seat belt for a rear seat of a passenger car to which a handicapped elderly person is mounted as described above, but a driver for a healthy person. For front seats and front seats
It can also be applied to a three-point seat belt for passengers of a car.

First, an outline of a seat belt system for an elderly person barrier-free according to an embodiment of the present invention will be described.

The seat belt system shown in FIG.
Although it is an extremely standard skeleton diagram also shown in the attached drawing of SD4604, the rear sheet 1 is equipped with a webping 2 in which a shoulder belt 2a and a lap belt 2b are connected.

An intermediate portion of the shoulder belt 2a is passed through an anchor-4 with an upper slip guide (a member for changing the direction of the webping 2 to bring it into a normal posture) attached to a rear pillar-3. The base end of the seat belt retractor 5 is wound up.

A lap belt 2b is connected to the tip side of the lap belt 2 and a tongue plate 6 is slidable but fixed at a predetermined position. That is, the tongue plate 6 is provided on the shoulder belt 2a. The tongue plate 6 can be inserted into and removed from a buckle 7 provided beside the rear sheet 1.

The buckle 7 is fixedly mounted on the vehicle body frame 8 so as to face forward and obliquely upward. Therefore, when the passenger wears the belt, the shoulder belt 2a is anchored.
4 and the buckle 7 firmly support the body at the time of impact.

In the seat belt system as described above, in this embodiment, as shown in FIG.
Belt insertion plate of the grate 6 (or slip guide if it is a tongue plate with a slip guide on the buckle side)
9, the following grip (also referred to as a hand-holding piece or finger-hanging piece) 10 is left on the tongue plate 6 attached to the shoulder belt 2a as it is without any processing such as drilling, and the attachment is attached thereto. As a result, it is attached by retrofit.

This grip 10 is made of soft synthetic resin (SB
S) injection-molded product, which is a loop-shaped grip portion 11, a rod body portion 12 integrated with the grip portion 11, and a rod body portion 12.
And a plate-shaped mounting portion 13 integrated with the above. Of course, the rod portion 12 may be omitted.

The plate-shaped mounting portion 1 of the grip 10
3 is a general existing (commercially available) metal tongue plate.
Can be attached to the belt insertion plate 9 of the
This grip 10 hangs below the anchor-4 with the upper slip guide when the webping 2 is not used,
In addition, it can be attached to this tongue plate 6 without play.
If the belt is not in a twisted posture, it is always in a state where it can be projected substantially horizontally toward the front of the vehicle body.

Therefore, even if the body comes into contact with the grip 10 when the user gets on and off, the shoulder belt 2a, which is a flexible synthetic fiber cloth belt, sways, and there is no problem in getting on and off.

Therefore, an elderly passenger sits on the rear seat 1 and grips the grip 10 which can be projected forward in the vicinity of the shoulder of the passenger or in the vicinity of the torso immediately next to the passenger. Put your finger on the shoulder and shoulder belt 2a
Is pulled out while resisting the winding force, the shoulder belt 2a is hung on the shoulder, and the tongue plate 6 is inserted into the buckle 7, so that the belt can be worn.

After this is worn, the grip 10 is in a state of being slanted forward and beside the rear seat 1, so that the dead space in the vehicle is utilized to occupy the seat or the adjacent space. Do not disturb passengers.

In particular, since the grip 10 that is substantially horizontal toward the front is gripped near the shoulder or the torso, the belt can be handled by elderly people (the fingers do not bend well, or the elbow joint is difficult to move). It is convenient for people who have weakened grip strength, etc., and can be used as a barrier-free item.

Next, the grip 10 of this embodiment will be described in detail.

FIG. 2 is an exploded perspective view, in which the grip 10 has the loop-shaped grip 11 as described above.
And a bar-shaped portion 12 integrally formed with the grip portion 11 and a plate-shaped mounting portion 13 integrated with the bar portion 12. The grip portion 11 has a size of a ping-pong ball. .

Therefore, the grip portion 11 has such a size that it can be easily wrapped by the palm of an elderly person, particularly an elderly person with a small hand, even when gripping while running.

The length of this rod portion 12 is about 10 to 15 cm.
Then, it has a tapered shape, which makes it easy to grip even if it is gripped by sandwiching it with, for example, two fingers. Therefore, the grip 10 is diversified in gripping form.

The rod body 12 or the grip portion 11 is gripped in a handy manner, and the shoulder belt 2a is pulled out from the seat belt retractor 5. Although the grip 10 is soft, it is extremely deformed. Less often
The tongue plate 6 can be inserted into the buckle 7 while holding the grip 10 that has been changed.

The plate-shaped mounting portion 13 is made of synthetic resin injection molding and has an elliptical shape when viewed from the front.
It is formed in a split manner, and together with the tongue plate 6, the piece-shaped base portion 16 of the rod body portion 12 is sandwiched from both sides thereof to form two screws 15,
It is fixed at 22 and integrated.

A square piece piece is formed on the base portion 16 of the rod body 12, and a screw through hole 14 is provided in this piece piece.

On the other hand, the plate-shaped mounting portion 13 divided into two pieces holds the piece-shaped base portion holding portions 18 and 18 for holding the piece-shaped base portion 16 therebetween.
And the belt insertion plate holding portions 19a and 19b for holding the belt insertion plate 9 of the tongue plate 6 are integrally formed.

Then, these piece-shaped base holding portions 18,
18 and the belt insertion plate holding portions 19a and 19b are opposed to each other and have substantially the same shape.
I am trying to sew and join with 2.

Therefore, the screw 15 is provided on one of the holding portions 18.
A boss 21 for screwing is provided, and a through hole 20 for inserting the screw 15 is provided in the other holding portion 18.

A boss 23 into which a screw 22 is screwed is attached to one (that is, the back side) of the belt inserting plate holding portion 19a.
And the other (that is, the front side) pinching portion 19b for the belt insertion plate is provided with a through hole 24 through which the screw 22 is inserted.

Further, these piece-shaped base holding portions 18, 1
8 are provided with arcuate ribs 25 facing the inner side thereof and fitted in the fitting groove 17 adjacent to the piece piece, respectively, so as to prevent the ribs from being pulled out and to be integrated with the grip, to set the orientation of the grip 10. I try not to delusion.

Further, the back and the front belt insertion plate holding portion 19
Notches 26 and 26 are provided in a and 19b, respectively, so that the shoulder belt 2a inserted into the insertion hole 9a of the belt insertion plate 9 does not hinder sliding movement.

That is, by the plate-shaped mounting portion 13 having the downward U-shaped notch recess 26, both the plate-shaped mounting portions on the front and back sides,
Since the tongue plate 6 is clamped from one side of the belt,
After the pinching, it exerts a characteristic that it does not hinder the operation of the current shoulder belt 2a.

The sandwiching portion 19 for both belt insertion plates
The a and 19b are provided with bent sides (inward flap pieces) 27 on the substantially outer circumferences of both plate bodies, and when the belt insertion plate 9 is sandwiched, the bent sides 27 and 27 are brought into contact with each other. The belt insertion plate 9 with a slight thickness is completely wrapped except for the lower part in the figure, and the plate-shaped mounting portion 13 is reinforced to provide safety, reliability, and rounded design as a seat belt system. Have secured.

Here, the grip portion 11 and the piece-shaped base portion 16
An annular deep groove multiple-type flexible shaft portion 28 as shown in FIG. 3 is integrally formed between the and, so that it does not bend due to the deep groove, but it is particularly softened to increase flexibility and is easily continuous. It is designed to be flexible in the state.

Therefore, if these grips 10
If there is discontinuous backlash or blurring (intermittent sudden transition) between the tongue plate 6 and the tongue plate 6, it is particularly uncomfortable for the user.

That is, when the grip 11 is gripped and there is a sudden displacement due to this rattling while the vehicle is traveling, for example, there is a feeling of slipping out, in particular, as described above, the whole is flexible, Pleasure will be strongly generated.

Therefore, in the grip 10 of this embodiment, when the grip 10 is added to the tongue plate 6 as an attachment, it is integrated with the tongue plate 6.

That is, although the tongue plate 6 is standardized, there is a slight dimensional difference (the plate thickness is substantially constant, but the plane shape is different) in the commercially available products. Because of this, this play does not distort, but I try to prevent this play.

That is, as shown in FIG. A pair of synthetic resin (ABS) injection-molded spacers 2 symmetrically arranged on both sides in the drawing in the belt insertion plate holding portion 19a on the back side.
9 and 29 are interchangeably used, and by interposing these spacers 29, vertical and horizontal play between the front and back holding portions 19a and 19b and the belt insertion plate 9 of the tongue plate 6 is eliminated. It has disappeared.

The spacer 29 is formed as a tree branch piece, and the downward arc portion 30 in FIG. 5 is formed in the branch portion. The pair of downward arc portions 30 of the belt insertion plate 9 are shown in FIG. 5
By contacting the upper corner portions 31, 31 with each other and contacting the lower side thereof with the bent side 27 of the belt insertion plate holding portion 19a on the back side, there is no backlash in the left and right and up and down directions.

As for this spacer 29, if two kinds or some kinds of spacers 29 having a slight dimensional difference in the thickness of the branch body are prepared, this grip 10 can be used with any of the commercially available tongue presses.
It is also generalized so that it can be applied to G6.

The backlash in the front-back direction in FIG.
Cushion seals for upper and left and right parts such as urethane foam
The tongue pieces 32, 33, 33 are attached to and absorbed by the inner surfaces of the front and back belt inserting plate holding portions 19a, 19b. That is, the play in the plate thickness direction of the tongue plate 6 is absorbed.

Therefore, when the grip 10 is gripped by the above-described backlash removal, the grip 1 is suddenly removed.
It eliminates the rattling that 0 goes out, and does not give anxiety to elderly people.

The spacer 29 is integrally formed with a branch-shaped hook portion 34 on the opposite side of the downward arc portion 30, and this is provided with a rib cutout portion in the belt insertion plate holding portions 19a and 19b on the front and back sides. 35 (see FIG. 3) is fitted and locked to be replaceable.

The grip 10 of this embodiment as described above is
A method of adding the belt to the existing vehicle body will be described.

FIGS. 3A, 3B and 4C,
In FIG. 3D, first, as shown in FIG. 3A, the piece-shaped base holding portion 18 on the back side of the pair of split plate-shaped mounting portions 13 is provided.
Then, the piece-shaped base portion 16 of the rod body portion 12 is fitted and the cushion sheet pieces 32, 33, 33 are attached (of course,
It may be pasted at the production plant).

The tongue plate 6 is temporarily placed (placed) there.
Then, one of the two types of paired spacers 29 prepared is selected to have no backlash, and the key notch 34 is fitted into the rib notch 35, whereby the downward arc portions 30 and 30 facing each other.
Of the tongue plate 6 that is in contact with the lower bent side 27.

Then, the tongue plate 6 is removed, and FIG.
As shown in (B), the belt inserting plate holding portion 19a on the back side is fitted from the back side of the shoulder belt 2a as indicated by a thick arrow.

Next, as shown in FIG. 4 (C), the belt insertion plate holding portion 19b on the front side sandwiches the tongue plate 6 from the back side of the shoulder belt 2a, and the belt on the back side is indicated by a thick arrow. It is joined to the insertion plate holding portion 19a.

Therefore, the shoulder belt 2a with the tongue plate 6 still attached does not twist the belt by coming into contact with the outer surface (front side) of the belt insertion plate holding portion 19b on the front side.

At this time, since the spacer 29 has a thickness protruding from the plate surface of the belt inserting plate holding portion 19a on the back side, the front belt inserting plate holding portion 19b has the same thickness. Fit in.

Then, the screws 15 and 22 are inserted into the through holes 20 and 24 on the front side and screwed.

As another embodiment, when the through holes 20 and 24 are formed in the belt inserting plate holding portion 19a 'on the back side, as shown in FIG. 4D, the shoulder belt 2a is formed. Is twisted 180 degrees, screws 15 and 22 are inserted and screwed into the through holes 20 'and 24' of the belt insertion plate holding portion 19a 'on the back side, and the grip 10 is attached to the tongue plate 6.

In this case, although the screws 15 and 22 are covered with the cap, the screws 15 and 22 are on the back side, so that the appearance is good.

In summary, the plate-shaped mounting portion 13 is divided into two in the thickness direction, and the belt insertion plate 9 of the tongue plate 6 is attached to the belt insertion plate holding portion 19a or 19b of one plate-shaped mounting portion 13. After the temporary placement, the spacer 29 is packed in the gap between the holding portion 19a or 19b and the belt insertion plate 9 to remove play, and then the other belt insertion plate holding portion 1
9g or 19a is a method for adding a grip, the tongue plate 6 is used as a grip mounting portion to avoid weakening of the belt, and the grip 10 as an attachment can be reliably rattled at the same time as mounting. The work can be visually performed, and thus the reliable general-purpose grip 10 can be provided.

[0074]

According to the present invention, since an elderly person or the like pulls out a belt by grasping a substantially horizontal grip hanging from the upper portion or the upper and lower middle portions at the side of the seat, the elderly person or the like can be worn. This makes it easier to handle the belt, increases the rate of wearing the belt, and prevents physical accidents.

In particular, since the grip is used as an attachment to the suspended tongue plate and the rattling is performed at the same time as the mounting work, the rattling which is disadvantageous to the grip having high flexibility is prevented, and the grip is aged. Don't give people anxiety.

Furthermore, this grip can be added to any commercially available tongue plate without rattling, and a general-purpose grip can be provided at low cost as a welfare tool.
