Acceleration detecting device
First Claim
1. An acceleration detecting device comprising:
- a hollow housing having a side wall, a closed end and an open end;
a cover closing the open end of the housing;
a weight pivotally mounted inside the hollow housing for rotating along a locus in response to an applied acceleration; and
a contact assembly adapted to be electrically closed through rotation of the rotated weight, the contact assembly including a main body and a pair of contacts embedded in the main body, the main body being positioned in the hollow housing along the side wall to support the contact assembly and keep the main body of the contact assembly off the locus of the weight during rotation of the weight.

Abstract
An acceleration detecting device includes a hollow housing having a side wall, a bottom wall and an opening and a cover closing the opening of the hollow housing. A weight is pivotally mounted in the hollow housing to be rotated about a locus in response to an applied acceleration. Also positioned within the housing is a contact assembly to be electrically-closed by the rotated weight. A plastic main body is held in the hollow housing along the side wall to support the contact assembly and keep the contact assembly spaced from the locus of the weight during the rotation of the weight. The plastic main body which supports the contact assembly may have a wider support along the side wall of the hollow housing, which is independent from fixture of the cover. Therefore, the contact assembly may be supported by the hollow housing through the main body in a more reliable manner. Further, the weight may rotate without any interference to the contact assembly because the contact assembly is kept off the locus of the weight.

5. An acceleration detecting device comprising:
-
enclosing means for enclosing an internal space, said enclosing means including a sidewall;
moving means positioned in the internal space for moving along a locus in response to an applied acceleration;
detecting means for detecting the movement of the movement means;
said detecting means including a main body and a pair of contacts embedded in the main body, the main body being positioned in the enclosing means along the side wall; and
holding means for holding the main body in the internal space to keep the main body of the detecting means off the locus of the moving means. - View Dependent Claims (6, 7, 8, 9)

10. An acceleration detecting device comprising:
-
a hollow housing having an open end and possessing a side wall having an outwardly projecting side wall portion;
a cover closing the open end of the housing;
a weight pivotally mounted inside the hollow housing for rotating in response to an applied acceleration;
a holder positioned within the hollow housing, said holder being separate from the hollow housing and secured in place within the hollow housing, said holder including a projection that engages the outwardly projecting side wall portion; and
a pair of electrodes mounted in the holder, said electrodes having end portions that are spaced apart from one another in a non-operational position of the weight, with the end portion of one of said electrodes being moved into contact with the end portion of the other electrode upon rotation of the weight. - View Dependent Claims (11, 12, 13, 14, 15)
