Claim 1
Independent Claim
192 words
In an automotive vehicle, the combination comprising, a source of pressure fluid, an inflatable cushion, communicating means actuatable to communicate the cushion with the source for inflation thereof, a bumper impact bar receptive of impact forces, means mounting the impact bar on the vehicle for movement relative thereto under impact forces, means absorbing the energy of impact forces applied to the bar within a predetermined limit, a pair of relatively movable telescopic members interconnected between the impact bar and the vehicle for movement relative to each other upon movement of the impact bar relative to the vehicle, an induction coil mounted on one of The members, a magnet slidably received within the coil, means positioning the magnet within the coil and locating the magnet a predetermined distance from the other member to permit telescopic movement of the members over such predetermined distance without movement of the magnet, telescopic movement of the members relative to each other over a distance exceeding such predetermined distance engaging the other member with the magnet to move the magnet relative to the coil and generate a voltage within the coil for initiating actuation of the communicating means.
Claim 2
Dependent Claim
192 words
In an automotive vehicle, the combination comprising, a source of pressure fluid, an inflatable cushion, communicating means actuatable to communicate the cushion with the source for inflation thereof, a bumper impact bar receptive of impact forces, means mounting the impact bar on the vehicle for movement relative thereto under impact forces, means absorbing the energy of impact forces applied to the bar within a predetermined limit, a pair of relatively movable telescopic members interconnected between the impact bar and the vehicle for movement relative to each other upon movement of the impact bar relative to the vehicle, an induction coil mounted on one of The members, a magnet slidably received within the coil, means positioning the magnet within the coil and locating the magnet a predetermined distance from the other member to permit telescopic movement of the members over such predetermined distance without movement of the magnet, telescopic movement of the members relative to each other over a distance exceeding such predetermined distance engaging the other member with the magnet to move the magnet relative to the coil and generate a voltage within the coil for initiating actuation of the communicating means.
Claim 3
Dependent Claim
232 words
In an automotive vehicle, the combination comprising, a source of pressure fluid, an inflatable cushion, communicating means actuatable to communicate the cushion with the source for inflation thereof, a bumper impact bar receptive of impact forces, means mounting the impact bar on the vehicle for movement relative thereto under impact forces, means absorbing the energy of impact forces applied to the bar within a predetermined limit, a pair of relatively movable telescopic members having respective ends thereof slidably interengaged, respective means connecting the other ends of the members respectively to the impact bar and to the vehicle for sliding movement of the members relative to each other upon movement of the impact bar relative to the vehicle, an induction coil mounted on one of the members adjacent the unconnected end thereof, a magnet slidably received within the coil, cooperating means on the coil and one member positioning the magnet within the coil and locating the magnet a predetermined distance from the unconnected end of the other member to permit telescopic movement of the members over such predetermined distance without movement of the magnet, telescopic movement of the members relative to each other over a distance exceeding such predetermined distance engaging the unconnected end of the other member with the magnet to move the magnet relative to the coil and generate a voltage within the coil for initiating actuation of the communicating means.
Claim 4
Dependent Claim
232 words
In an automotive vehicle, the combination comprising, a source of pressure fluid, an inflatable cushion, communicating means actuatable to communicate the cushion with the source for inflation thereof, a bumper impact bar receptive of impact forces, means mounting the impact bar on the vehicle for movement relative thereto under impact forces, means absorbing the energy of impact forces applied to the bar within a predetermined limit, a pair of relatively movable telescopic members having respective ends thereof slidably interengaged, respective means connecting the other ends of the members respectively to the impact bar and to the vehicle for sliding movement of the members relative to each other upon movement of the impact bar relative to the vehicle, an induction coil mounted on one of the members adjacent the unconnected end thereof, a magnet slidably received within the coil, cooperating means on the coil and one member positioning the magnet within the coil and locating the magnet a predetermined distance from the unconnected end of the other member to permit telescopic movement of the members over such predetermined distance without movement of the magnet, telescopic movement of the members relative to each other over a distance exceeding such predetermined distance engaging the unconnected end of the other member with the magnet to move the magnet relative to the coil and generate a voltage within the coil for initiating actuation of the communicating means.
Claim 5
Dependent Claim
35 words
The combination recited in claim 2 wherein the cooperating means include a fixed stop on the coil and biasing means seating between the one member and the magnet seating the magnet against the fixed stop.
Claim 6
Dependent Claim
62 words
The combination recited in claim 2 wherein the coil is wound on an annular spool having a central bore coaxial with the axes of the telescopic members and defined by an annular wall, the cooperating means including a radial rib on the annular wall and a bias seated between the one member and the magnet to seat the magnet against such rib.
