DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an external perspective view of an automobile, FIG. 2 is a plan view thereof, and FIG. 3 is a sectional view taken along line III-III of FIG. In these figures, the symbol F indicates the forward direction of the vehicle, and the symbol W indicates the width direction of the vehicle body 1. In the following description, the forward direction F is referred to as “front”, the opposite direction is referred to as “rear”, and the left and right directions with respect to the forward direction F are referred to as “left and right”.

The body 1 of the automobile shown in FIGS.
A roof panel 2 constituting the upper wall thereof;
A front header 3 fixed to the front of the vehicle body 1 and extending in the width direction W of the vehicle body 1, a pair of front pillars 4 extending diagonally downward from the left and right front ends of the roof panel 2, and extending diagonally downward from the left and right rear ends of the roof panel 2. A pair of rear pillars 5, left and right front fender panels 8, a hood 6 covering an upper part of an engine room, a luggage door 7 covering an upper part of a luggage room, a front side door 9 which is freely openable and closable at a side door opening, a rear part. Side door 10 and width direction W of body 1
And a large number of members such as a cross member 11 extending in the direction. In addition, both front pillars 4 and roof panel 2
A front glass 12 is fixed to a front window opening defined by the cross member 11 and a rear glass 13 is similarly fixed to a rear window opening. Further, window glasses 14 and 15 are supported on the respective doors 9 and 10 so as to be able to move up and down, respectively, and the window openings on the side of the vehicle body are covered with these window glasses 14 and 15.

A vehicle compartment R is defined inside the vehicle body, and a ceiling member 16 that covers the interior surface of the roof panel 2 is located above the vehicle compartment R.

Although not shown in the drawing, a driver's seat, a passenger seat, and a rear seat located behind these seats are arranged in the passenger compartment, and an occupant sitting on these seats is seated. The webbing of the belt device is worn on the body, and the automobile is run in this state. Therefore, even when the vehicle collides or rolls over during the traveling, safety for the occupant is ensured.

[0012] However, the vehicle is run with luggage (not shown) mounted on a seat or the like without being fixed, and the vehicle collides or rolls over.
In the case where the vehicle 2 is damaged, in a conventional vehicle, as described above, the luggage is thrown out of the front window through the window opening, and the luggage may be damaged. In order to prevent such a problem, the following configuration is employed in the vehicle of the present embodiment.

First, a collision sensor 17 (FIG. 2) for detecting a collision of a vehicle is provided in an appropriate place of the vehicle, for example, in an engine room. To detect a car collision.

In the vicinity of the upper end of the windshield 12, there is disposed a protrusion preventing member 18 made of a flexible material. The protrusion preventing member 18 is usually provided with the roof panel 2 forming the upper wall of the vehicle body 1, and It is housed in the space between the ceiling member 16 located in the upper part of the vehicle compartment and in a small and folded state. Therefore, normally, the pop-out prevention member 18 is not visually recognized by the occupant in the vehicle cabin.
The pop-out preventing member may be made of a flexible sheet material or the like.
It is composed of a flexible net made of high strength resin or cloth (see FIG. 7).

The above-mentioned flexible projection preventing member 18
As shown in FIG. 4 on an enlarged scale, one end side 18A has
It is firmly fixed to the vehicle body 1. In the illustrated example, one end side 18 </ b> A is firmly fixed to the front header 3 of the vehicle body 1 by a large number of clips 19.

The other end 18B of the protrusion preventing member 18
Is firmly connected to the cable 20, and this cable 20
Is the width W of the vehicle body 1 between the roof panel 2 and the ceiling material 16.
(See FIG. 1). Also, as shown in FIG.
A surface of the front pillar 4 facing the interior of the vehicle is covered by a front pillar garnish 21, which is locked to the front pillar 4 by a clip 22, and a gap between the garnish 21 and the front pillar 4. The cable 20 extends downward.

As shown in FIG. 2, cylinders 23 fixed to the vehicle body 1 are arranged inside the left and right front fender panels 8, respectively. As shown in FIG. The pistons 24 are respectively slidably arranged in the axial direction of the cylinder 23. Thus, each cylinder 23 slidably houses each piston 24. A cable 20 extending downward along each front pillar 4 slidably penetrates an upper end wall 23A of each cylinder 23, and has a piston 24 at each lower end thereof.
Are firmly connected to each other.

When a running car causes a collision accident or rolls over, the above-mentioned collision sensor 17 detects the deceleration of the car at this time, and detects a collision of the car. The detection signal is input to the gas generator 25 shown in FIG. As the gas generator, for example, an inflator conventionally used in an air bag system or the like can be adopted. The gas generator 25 is configured such that the ignition device is ignited by the above-described detection signal and the gas generating agent is instantaneously discharged. It is configured to burn. The gas thus generated is supplied to an upper working chamber 26 defined by a cylinder 23 and a piston 24, whereby each piston 24 moves downward at a high speed, and the cable 20 pulls downward with a large force. And the protrusion preventing member 1 coupled to the cable 20.
The other end 18B of 8 is strongly pulled downward. In this manner, the protrusion preventing member 18 that has been stored in the folded state is pulled downward along the front window opening as shown by an arrow A in FIG. 8, and as shown in FIG. Cover the entire window opening. One end 18A of the protrusion preventing member 18 remains fixed to the front header 3 of the vehicle body 1.

When the cable 20 and the protrusion preventing member 18 move downward, they do not hinder the movement.
The ceiling material 16 is deformed or broken in the direction indicated by the arrow B in FIG. Similarly, the front pillar garnish 21 is deformed or broken in the direction indicated by the arrow C in FIG.

As described above, the gas generator 25 is divided by the cylinder 23 and the piston 24 so as to move the piston 24 in the cylinder 23 downward when the collision sensor 17 detects the collision of the vehicle. A gas is supplied to the working chamber 26, whereby the protrusion preventing member 1 is
8 extends downward and covers the entire front window opening. For this reason, even if the windshield 12 is damaged by the impact applied to the vehicle body 1 or the windshield 12 (FIG. 8)
), It is possible to prevent luggage in the vehicle compartment from being thrown out through the window opening on the front side.

As described above, the vehicle of this embodiment has a drawer for pulling the other end of the protrusion preventing member so that the protrusion preventing member covers the window opening of the vehicle body when the collision sensor detects the collision of the vehicle. In the example shown, the cable 20, the piston 24, and the cylinder 2
3 and the gas generator 25 constitute the above-mentioned drawing means.

As described above, when the accident occurs, the protrusion preventing member 18
Although the example in which is described so as to cover the window opening on the front side has been described, the protrusion preventing member may be configured to cover the window opening on the rear side or the window opening on the side of the vehicle body. In the event of an accident, it is most preferable that all the window openings on the front and rear sides and the window opening on the side of the vehicle body be covered by the respective protrusion preventing members. With this configuration, it is possible to more reliably prevent a problem that the baggage in the vehicle compartment is thrown out.

The present invention can be widely applied to various types of automobiles other than the illustrated type.

[0024]

According to the first aspect of the present invention, when a large external force is applied to the vehicle body, it is possible to prevent a problem that an object in the vehicle compartment is thrown out through the window opening due to the impact.

According to the second aspect of the present invention, the drawer can be configured simply and at low cost.
