Reference numeral 20 is an electric slide door, and reference numerals 30, 40, 50 are pinch prevention devices attached to the end face step portion 23 of the electric slide door 20, and pinch sensors 61, 62, 63.
Is built in. 18 is the outside of the vehicle, 19 is the interior, 70 is the front side, 71 is the rear side, 72 is the left side of the automobile, and 73 is the right side of the automobile.

The pinching prevention device 30 shown in FIG. 3 will be described in detail. The cored bar 25 is embedded in the flange 22 protruding from the end face step 23 of the electric slide door 20, and the U-shaped portion 31 is embedded. And a hollow portion 32 integrally connected to the tip of the U-shaped portion 31. Further, the sandwiching sensor 61 is built in the hollow portion 32.

In operation, when the electric sliding door 20 is closed, the body opening edge portion 10 of the automobile is closed.
When a part of the human body exists between the vertical end surface 11 of the electric sliding door 20 and the vertical end 21 of the electric sliding door 20, the pinching sensor 61 detects the signal, and receives the signal, for example, and the electric sliding door 20
The vertical end surface 1 of the body opening edge portion 10 is configured by stopping the motor that drives the vehicle (not shown).
It is possible to prevent an accident in which a part of a human body such as a limb is sandwiched between 1 and the vertical end 21 of the electric slide door 20 and an injury is caused.

Explaining the second embodiment,
As shown in FIG. 4, the weather strip 40 has a U-shaped cross section in which the metal core 25 is embedded, and is fitted to the flange 22 projecting from the end face step 23 of the electric slide door 20, and the tip portion thereof is attached. From the interior to the room 19 side, cross section L
A character-shaped sandwiching sensor 62 is built in. The pinch sensor 62 detects the direction of the front 70 rear 71 and right and left 7
It has two directions of 2, 73, and is wider in the front, back, left, and right, and the sensing range is widened, further improving safety.

The third embodiment will be described with reference to FIG. 5. The weather strip 50 has a built-in pinch sensor 63 composed of two linear cross-section portions 64 and 65 which are orthogonal to each other in an L shape. ing. The pinch sensor 63 is 2
Since the book is divided into the linear portions 64 and 65, the book strip is easily incorporated into the weather strip 50 and the workability is improved.

[0017]

According to the first invention shown in FIG. 3, a part of a human body such as a limb is provided between the vertical end surface 11 of the body opening edge portion 10 of the automobile and the vertical end 21 of the electric sliding door 20. Accidents of being pinched and injured are prevented.

According to the second invention shown in FIG. 4, since the sensing range is expanded, the safety is further improved.

According to the third aspect of the invention shown in FIG. 5, it is easy to assemble it into the pinch prevention device and the workability is improved.
