As shown in FIG. 2, the spring 25 normally holds the stopper member 21 in the recess 23 by locking the stopper member 21 to the rear of the vehicle on the mass 24 and storing the stopper member 21 in the recess 23. When a force is applied, as shown in FIG. 3, the mass 24 is allowed to slide toward the front of the vehicle due to the inertial force, and the stopper member 2 by the locking member 27 is allowed.
The lock of No. 1 is released, and the stopper member 21 is allowed to stand up by the biasing force of the spring member 26.

Now, as shown in FIGS. 1 and 2, the floor 1
When a load 11 is loaded on the vehicle 2 and the stopper member 21 is housed in the recess 23 and an impact force (e.g., collision) of a predetermined value or more is applied to the vehicle, the mass 2 is generated by the inertial force.
4 overcomes the urging force of the spring 25 and moves to the front of the vehicle, the stopper member 21 is disengaged from the locking member 27 and is rotatably erected on the floor 12 by the spring member 26, and the luggage 11 abuts on the stopper member 21. The luggage 11 is prevented from colliding with the rear seat back. When a collision occurs, the stopper 21 projects above the floor 12, and the stopper 2
Since 1 is stored in the recess 23, it does not get in the way.

A plurality of luggage movement prevention mechanisms 20 may be provided in the vehicle width direction, or one luggage movement prevention mechanism 20 may be provided in substantially the same length as the floor 12 in the vehicle width direction.

FIG. 4 shows a second embodiment of the present invention. The luggage movement prevention mechanism 30 according to the present embodiment includes a stopper member 31 for preventing movement of the luggage 11 and a stop member 2 on the floor 12 when an impact force of a predetermined value or more is applied to the vehicle.
It has a bracket 32 as an operating means for projecting 1 by inertial force.

On the floor 12, an inclined surface 33a whose cross section in the vehicle front-rear direction is inclined downward toward the vehicle front,
A concave portion 33 is formed by a vertical wall surface 33b provided continuously to the inclined surface 33a. The bracket 32 is screwed to the inclined surface 33 a of the recess 33 with a bolt 34. A shaft portion 35 that rotatably supports the stopper member 31 is formed on the bracket 32.

The stopper member 31 is normally provided with an inclined surface 33.
It is stored in a state of being laid down on a, and when the impact force is applied to the vehicle, the inertial force causes the shaft 35 to pivot about the shaft portion 35 as shown by a phantom line in FIG.
It is supported by abutting against and is prevented from rotating forward of the vehicle.
The luggage 11 contacts the stopper member 31 and is prevented from colliding with the rear seat back.

FIG. 5 shows a third embodiment of the present invention. The luggage movement prevention mechanism 40 according to the present embodiment includes a stopper member 41 for preventing movement of the luggage 11 and a stop member 4 on the surface of the floor 12 when an impact force of a predetermined value or more is applied to the vehicle.
And an actuating means for projecting 1. The stopper member 41 includes a bracket 44 fixed to the lower surface of the floor 12.
Is rotatably supported by the shaft 44a.

The actuating means rotates the G sensor 43 as a detecting means for detecting the impact force applied to the vehicle, and the stopper member 41 when the G sensor 43 detects the impact force, around the shaft 44a in front of the vehicle. And a projecting means 42 for projecting onto the floor 12.

The projecting means 42 includes an operating piece 45 fixed to the base end of the stopper member 41, a wire 46 having one end connected to the operating piece 45, and a piston 47 connected to the other end of the wire 46. The cylinder 48 that slidably supports the piston 47 and the cylinder 4 that is provided on the lower surface of the floor 12
8 includes a bracket 49 for supporting 8 and an explosive 50 for feeding air into the cylinder 48 and moving the piston 47. In the figure, reference numeral 51 is a stopper member 41.
Is held on the same plane as the floor 12, and the stopper member 4
1 is a stopper that restricts the rotation of the vehicle 1 toward the rear of the vehicle.

In the above structure, when an impact force of a predetermined value or more is applied to the vehicle, the G sensor 43 detects this impact force and explodes the explosive powder 50. When the explosive powder 50 explodes, combustion gas flows into the cylinder 48, the wire 46 moves in the direction of the arrow together with the piston 47, the operating piece 45 rotates about the shaft 44a, and the stopper member 41 projects onto the floor 12. Let The luggage 11 abuts on the stopper member 41 protruding above the floor 12, and is prevented from colliding with the rear seat back.

FIG. 6 shows a modification of the embodiment shown in FIG. This modification is different from the embodiment shown in FIG. 5 only in that instead of the explosive powder 50 of the projecting means 42, a spring 53 for sliding the piston 47 and a pin 54 for preventing the movement of the piston 47 are arranged. Is different.

Similarly to the above-described embodiment, when the G sensor 43 detects an impact force of a predetermined value or more, the pin 54 is pulled out by an appropriate means, and the urging force of the spring 53 causes the wire 46 together with the piston 47 in the arrow direction. The stopper member 41 moves, the stopper member 41 is projected onto the floor 12, the luggage 11 abuts on the stopper member 41, and the luggage 11 is prevented from colliding with the rear seat back.

[0029]

According to the present invention, when an impact force of a predetermined value or more is applied to the vehicle, the actuating means causes the stopper member to project above the floor surface to bring the luggage in the luggage compartment into contact with the stopper member. Even if the seat back is not reinforced, luggage can be prevented from entering the passenger compartment, and a lightweight and inexpensive luggage movement prevention mechanism can be provided.
