Description

[Detailed explanation of the idea] The present invention relates to improvements in seat belt devices.

Conventionally, for example, a seat belt with one end wound around a retractor with an emergency locking mechanism attached to a door was inserted through a through ring in the upper part of the retractor in the door, and was disposed so as to cross the front of the occupant. Seat belt devices are known. In addition, with the seat belt device described above, when the door is suddenly opened in an attempt to rescue the occupant after an accident, the retractor may become locked or remain locked, resulting in the door opening only slightly. There is a problem. In order to solve this problem, a device is also known in which the through ring is removably attached to the door via a buckle or the like.

However, even in this type of device, the seat belt may be retracted by the retractor as soon as the through ring is removed, and the retractor may remain locked in the direction in which the belt is pulled out. However, there was a problem in which the door could only be opened a little, which prevented the rescue of passengers from being resolved.

The present invention was devised to solve the above-mentioned problems, and a seat belt with one end wound around a retractor with an emergency locking mechanism attached to the door of a car is attached to the door above the retractor. The door is arranged so as to pass through a through-ring and cross the front of the occupant, and the through-ring is removably attached to the door,
The seatbelt is disposed between the through ring and the retractor in the door, and allows the seatbelt to be inserted loosely, and when the throughring is removed from the door, the seatbelt is wound up by the winding force of the retractor. a stopper member for stopping the
When a large force exceeding the winding force of the retractor is applied to the seat belt while the seat belt is locked to the stopper member, the stopper member deforms or breaks, causing the seat belt to become unlatched. The seat belt device is characterized in that it is configured to include a weakened portion provided therein.

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

In the first embodiment shown in FIGS. 1 to 4, reference numeral 2 in the drawings is a seat attached to the floor of the vehicle interior, and 4 is a door located on the side of the seat, whose front edge is pivoted to the vehicle body. , 6 is an anchor fixed to the bottom of the door, 8 is a retractor fixed to door 4, 10
12 is a buckle attached to the upper part of the door 4, 12 is a buckle attached to the side of the seat 2, 14 is a through tongue detachably attached to the buckle 10, and 16 is a through tongue detachably attached to the buckle 12. be. A seat belt 18 is wound around the retractor 8 and is passed through the through tongue 14 and the through tongue 16 in this order, and its tip is connected to the anchor 6. Note that 20 is a striker attached to the door 4 together with the buckle 10, and 22 is a catch fixed to the rear pillar of the door 4. When the door 4 is closed, the striker 20 and the catch 22 engage with each other. When a large force is applied to the buckle 10 through the seatbelt 18 and the through tongue 14 due to an accident, the striker 20 is activated to the catch 22.
The striker is configured to be locked so that the striker will not be displaced forward due to deformation of the door 4.
In this embodiment, a stopper member 26 into which the belt 18 is loosely inserted is inserted between the belt outlet 24 and the through tongue 14 on the inner wall of the door 4.
is installed. The stopper member 26 is preferably made of a highly elastic material such as rubber or plastic, and as shown in FIG. A slit 28 is provided for loose insertion.

According to the above configuration, in the seat belt device shown in FIG. 1, when the door 4 is suddenly opened to rescue the occupant on the seat 2 after an accident, the retractor 8 is locked and
Even if it opens only slightly, the through tongue 14 can be removed from the buckle 10 by operating the buckle 10 through the gap. Even if the seat belt 18 is retracted by the retractor 8 as soon as it is removed, the seat belt will be stretched between the through tongue 16 and the stopper member 26, and if the door 4 is opened further, the stopper member 26 will be pulled up. The member 26 is deformed and the belt 18 becomes the same stopper member 2.
6 and the door 4 can be opened until the belt 18 is tensioned between the belt outlet 24 and the through tongue 16. That is, this embodiment has the effect that the door 4 can be opened an additional distance approximately equal to the distance between the belt outlet 24 and the stopper member 26 compared to the conventional device described above.

The second embodiment shown in FIG.
The slit 32 at 0 is provided at a different position compared to the member 26 shown in FIG. In the third embodiment shown in FIG. 6, a stopper member 34 attached to the inner wall of the door 4 is made of thick vinyl or paper, and a perforation 36 is provided in the center so that the stopper member can be easily broken. It has been established.

In these second and third embodiments, the same effects as in the first embodiment can be obtained.

In addition, in each of the above embodiments, the seat belt 18
The tip of the seat belt 18 is connected to the anchor plate 6 fixed to the door 4, but as shown in FIGS. 7 and 8, a tongue 38 is attached to the tip of the seat belt 18.
If the tongues are connected and removably attached to the buckle 40 fixed to the door 4, the door 4 can be opened more widely during rescue after an accident. According to the present invention, when a person outside the car suddenly tries to open the door to rescue the occupants trapped inside the car after a collision, even if the door opens only a little, Remove the through ring from the door through the gap,
After that, if you pull the door with a strong force, it has the effect of opening the door wide.
