Abstract

An entrapment prevention sensor detecting an entrapment of an obstacle between an opening and closing door of a vehicle constituting a first member and including a corner portion and a periphery of a body opening portion constituting a second member, includes a protector including an assembly portion and a hollow portion, the assembly portion assembled onto a fitting flange provided at one of the first and second members, the assembly portion prevented from being provided at the corner portion, a sensor main body accommodated within the hollow portion, and a corner member provided at the corner portion and including a receiving portion and a fixed plate portion, the receiving portion having a hollow and curved shape corresponding to a shape of the corner portion and accommodating the sensor main body, the fixed plate portion including a clip bore and fixed to the fitting flange by means of a clip.

Claims

1. An entrapment prevention sensor for an opening and closing door of a vehicle, the entrapment prevention sensor detecting an entrapment of an obstacle between an opening and closing door constituting a first member and including a corner portion and a periphery of a body opening portion constituting a second member and relative to which the opening and closing door approaches and separates, comprising:

a protector made of an elastic member and including an assembly portion and a hollow portion that is integrally formed with the assembly portion, the assembly portion having a U shape in cross section and being assembled onto a fitting flange provided at one of the first and second members, the assembly portion prevented from being provided at the corner portion;

a sensor main body accommodated within the hollow portion of the protector;

a corner member provided at the corner portion and including a receiving portion and a fixed plate portion that is integrally formed with the receiving portion, the receiving portion having a hollow and curved shape corresponding to a shape of the corner portion and accommodating the sensor main body, the fixed plate portion including a flat plane shape and a clip bore and fixed to the fitting flange by means of a clip; and

wherein the corner member includes two plate members overlapping each other, and a portion of the receiving portion facing the fixed plate portion is divided into two parts, which are integrally connected to the respective plate members to form a split pin shape.

2. An entrapment prevention sensor for an opening and closing door of a vehicle, of a power driven opening and closing type and including a corner portion, the entrapment prevention sensor detecting an entrapment of an obstacle between the opening and closing door and a body, comprising:

a protector made of an elastic member and including an assembly portion and a hollow portion that is integrally formed with the assembly portion, the assembly portion having a U shape in cross section and being assembled onto a fitting flange provided at the opening and closing door;

the protector prevented from being provided at the corner portion;

a sensor main body accommodated within the hollow portion of the protector;

a corner member provided at the corner portion and including a receiving portion and a fixed plate portion that is integrally formed with the receiving portion, the receiving portion having a hollow and curved shape corresponding to a shape of the corner portion and accommodating the sensor main body, the fixed plate portion including a flat plane shape and a clip bore and fixed to the fitting flange by means of a clip; and

wherein the corner member includes two plate members overlapping each other, and a portion of the receiving portion facing the fixed plate portion is divided into two parts, which are integrally connected to the respective plate members to form a split pin shape.

3. An entrapment prevention sensor for an opening and closing door of a vehicle, of a power driven opening and closing type and including a corner portion, the entrapment prevention sensor detecting an entrapment of an obstacle between the opening and closing door and a body, comprising:

a protector made of an elastic member and including an assembly portion and a hollow portion that is integrally formed with the assembly portion, the assembly portion having a U shape in cross section and being assembled onto a fitting flange provided at the opening and closing door;

the protector configured only by the hollow portion at the corner portion of the opening and closing door;

a sensor main body accommodated within the hollow portion of the protector;

a corner member provided at the corner portion and including a receiving portion and a fixed plate portion that is integrally formed with the receiving portion, the receiving portion having a hollow and curved shape corresponding to a shape of the corner portion and accommodating the hollow portion, the fixed plate portion including a flat plane shape and a clip bore and fixed to the fitting flange by means of a clip; and

wherein the corner member includes two plate members overlapping each other, and a portion of the receiving portion facing the fixed plate portion is divided into two parts, which are integrally connected to the respective plate members to form a split pin shape.

4. An entrapment prevention sensor for an opening and closing door of a vehicle, the entrapment prevention sensor detecting an entrapment of an obstacle between an opening and closing door constituting a first member and including a corner portion and a periphery of a body opening portion constituting a second member and relative to which the opening and closing door approaches and separates, comprising:

a protector made of an elastic member and including an assembly portion and a hollow portion that is integrally formed with the assembly portion, the assembly portion having a U shape in cross section and being assembled onto a fitting flange provided at one of the first and second members, the assembly portion prevented from being provided at the corner portion;
