Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-outside-out prevention device for preventing an occupant from being thrown out from a window opening on a side surface of a vehicle body due to sudden turning, overturning, or the like of an automobile.

[0002]

2. Description of the Related Art An automobile is provided with a seat belt 3 on a front seat 2 of a vehicle body 1 as shown in FIG. 8 in order to secure a driving posture and reduce accidents. A perforated anchor plate 4 is attached to the upper end of the seat belt 3, and the anchor plate 4 is supported by a pin 6 fixed to the upper part of the center pillar 5 so that the seat belt 3 can swing. A tongue plate 7 for connection is held at an intermediate portion of the seat belt 3, and the tongue plate 7 is used for the seat 2.
It is adapted to be connected to a buckle 8 provided on the lateral side of the. A retractor with a pretensioner (belt winding device) 9 is provided at the lower part of the vehicle body. The retractor 9 extends the seat belt 3 and restrains the occupant so that the occupant is kept in a sitting posture when the seat belt 3 is worn (see Japanese Patent Laid-Open No. 1-240345).

By the way, a front windshield 11 and a door glass 12 are mounted on front and side windows of an occupant, supported by a front pillar 10. And
When the occupant wears the seat belt 3, the occupant is prevented from colliding with these glasses and being thrown out of the vehicle.

The front pillar 10 is also disclosed in Japanese Utility Model Laid-Open No. 60-52172. The outline of this will be described with reference to FIG. The front pillar 10 is composed of a front pillar inner 13 and a reinforcing member 14 on the inner side, a front pillar outer 15 on the outer surface, and a front pillar trim on the outer inner surface.
It consists of 16. Also, front pillar inner 13
The end portions of the reinforcing member 14 and the front pillar outer 15 are connected via a weather strip 17. Further, the protrusion 18 on the inner side of the weather strip 17 is engaged with the end portion of the front pillar trim 16. In addition, the windshield 11 is connected via a molding 19 and is connected to the door glass.
12 is connected to a door panel 21 via a weather strip 20.

[0005]

As described above, there is no problem if the seat belt 3 is worn, but if the seat belt 3 is forgotten, the occupant may suddenly turn, roll over, etc. It may be moved according to the external force, and when the external force is large, it may be thrown out of the vehicle from the wind in the empty space. Further, even if an occupant sitting on the wind side of the vehicle body wears the seatbelt 3, if another occupant does not wear the seatbelt 3, a sudden external force may cause the passenger to be thrown out of the vehicle. There is.

A vehicle rollover accident or the like generally has a long duration, and the retractor 9 for the seat belt 3 once locked.
May be released by reaction, or may be released from the restraint of the seat belt 3 due to lateral displacement of the occupant, and if it is released in this way, it may be thrown out of the vehicle.

It is an object of the present invention to provide a vehicle pop-out prevention device that supports an occupant when the vehicle suddenly turns or rolls, in addition to the seat belt.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention swingably attaches one end of a protect belt to an upper portion of either a front pillar or a center pillar surrounding a side window of an automobile. , A retractor with a pretensioner for winding the other end of the protect belt on the diagonal of the upper part of the one side is provided, and an intermediate part of the protect belt is housed so as to project into the trim along the edge of the side window, It is characterized in that an acceleration sensor for operating the retractor with a pretensioner is provided.

[0009]

Since the present invention is configured as described above, when the acceleration sensor detects a strong impact such as a collision of an automobile, the retractor with a pretensioner operates and the protect belt is wound up. .. Normally, the protect belt housed in the trim along the edge of the side window is projected by this tension and stretched on the diagonal line of the side window.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the seat belt 3 shown in the related art is not shown. As shown in FIG. 1, a front pillar 10 and a center pillar 5 are arranged on the side of the side window 22 of the vehicle body 1, and a roof side rail 23 is bridged above the front pillar 10. The pop-out prevention device 24 is one in which a protect belt 25 is stretched over the middle portion (on the diagonal line in the embodiment) of the side window 22, the anchor plate 4 is provided at the end portion of the protect belt 25, and the center pillar 5 It is swingably attached to a pin 6 attached to the upper portion (see FIG. 4). Further, a retractor 9 with a pretensioner is provided inside the instrument panel 26 at the lower part of the front pillar 10, and the other end of the protect belt 25 is wound. As shown in FIG. 7, a guide 27 is attached to the retractor 9 so that the protect belt 25 can be quickly wound without being twisted.

The protect belt 25 hung from the anchor plate 4 to the retractor 9 is a roof side rail.
23 is disposed along the front pillar 10, and normally, the protect belt 25 is provided on the front pillar 10 as shown in FIG.
Hidden behind the front pillar trim 16 of. FIG. 3 shows a cross section of the joint portion of the front pillar trim 16. An acceleration sensor 28 for detecting a collision for operating the retractor 9 is attached to the cowl 29 (or the center tunnel 30).

The operation of the pop-out prevention device 24 when a vehicle collides will be described with reference to FIG. First, a shock is input (step), transmitted to the acceleration sensor 28 (step), and the acceleration sensor 28 inputs the output to the CPU.
In the CPU, the determination unit determines whether the input signal is due to a collision (step). In the judgment section,
If YES, the retractor 9 is operated to start winding the protect belt 25 (step). If NO, the normal condition will be maintained.

When the retractor 9 is actuated and the protect belt 25 is wound up, the protect belt 25 becomes tense and short, and the front pillar trim 16 is pushed open to pop out (see FIG. 5).
(See), crossing the side window 22 diagonally. When the occupant is swung outward due to the collision, the protect belt 25 receives the occupant, which prevents the occupant from jumping out of the vehicle. Further, since the protect belt is arranged along the roof side rail 23 and is covered by the front pillar trim 16, it does not disturb the normal state and does not impair the appearance.

It should be noted that the end of the weather strip 17 may be lightly hooked to the front pillar trim 16, so that when tension is applied to the protect belt 25, the protect belt 25 easily pushes the front pillar trim 16 open and pops it out. Become so. Also, front pillar trim
A clip may be used to fix the 16 to the front pillar inner 13, or it may be fixed to the windshield side so that the protect belt 25 can be easily pulled out. In addition, in the case of a vehicle equipped with an airbag, the acceleration sensor 28 can be shared.

[0015]

Since the present invention is configured as described above, the acceleration sensor detects a shock such as a vehicle collision or a rollover, and the protect belt is hung diagonally on the side window. When it moves to the side window due to an impact, it collides with the protect belt and it is possible to prevent the occupant from jumping out of the vehicle.Because it is a belt type, it can stretch a little and absorb the kinetic energy of the occupant. As a result, damage to passengers is reduced. In addition, the occurrence of secondary accidents due to jumping out of the vehicle can be reduced.
