DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. 1 and 2 show an embodiment of a rear window safety net device according to the present invention.
With respect to the car body 11 of a car such as a box, a header trim 13 detachably mounted inside the car body 11 and an upper end thereof are directly attached to a part 11a of the car body 11 at an upper portion of a rear window 12 provided at a rear portion thereof. Attached and the lower end is attached to the header trim 13;
And a protection net 14 housed in the header trim 13 in a folded state.

The header trim 13 is formed entirely of a resin containing reinforcing fibers, for example, and has a center hole 15a on its inner surface and a flange 15b at the upper end, as shown in detail in FIG. An engaging portion 15 is provided, and the engaging portion 15 is mounted on the vehicle body 11 by fitting the engaging portion 15 to a positioning pin 16 planted on the inner surface of the vehicle body. Here, as shown in FIG. 3, the header trim 13 is configured such that the locking portion at the tip of a lever-shaped stopper 17 that is swingably attached to the vehicle body 11 engages with the flange portion 15 b of the engaging portion 15. By doing so, it can be held in the mounted state.

For example, a wire 18 is connected to the stopper 17, and the wire 18 is connected to a driving device 23 that operates based on an impact detection signal from an impact sensor 22 such as a seat belt pretensioner system or an airbag system (not shown). Connected to the impact sensor 22
When the drive device 23 is actuated by detecting the impact, the wire 18 is pulled in the direction of the arrow in FIG. 3 so that the stopper 17 rotates and comes off the flange portion 15b of the engagement portion 15. I have. That is, the drive device 23 and the wire 18 constitute an unlocking device.

A coil spring 19 and a disk 20 are fitted on the positioning pins 16, and when the header trim 13 is locked at the mounting position, the engaging portion attached to the header trim 13 is engaged. 15 flanges 1
