Abstract
Abstract A fire protection device is mounted in an automobile and includes a switch responsive to a severe shock caused in an accident. An explosive cartridge is electrically connected to the switch for detonation and is mounted in a hollow body. A shaft having one end normally adjacent to the hollow portion of the body supports a switch blade normally connected in the ignition circuit and is adapted to engage a lever for operating a fire extinguisher. The shaft is slidably mounted and guided for movement between several columns. In response to a severe shock the explosion of the cartridge causes the shaft to move from its normal position thereby simultaneously opening the ignition circuit and actuating a fire extinguisher. All the elements but for the shock responsive switch are preferably mounted on a single support on the body of the automobile.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
In a fire protection device for use in motor vehicles having an ignition circuit including a shock-responsive means, an explosive charge and a detonating means operatively connected to the shock-responsive means for igniting the explosive charge in response to a severe shock comprising: an operating mechanism for opening the ignition circuit of the motor vehicle and for actuating a fire-extinguishing unit including an operating member mounted for translation between a first position adjacent to the explosive charge and a second position remote therefrom, and adapted to be driven from its first position to its second position to open the ignition circuit and to actuate the fireextinguishing unit by the detonation of the explosive charge in response to a severe shock.
Claim 2
Dependent Claim
120 words
In a fire protection device for use in motor vehicles having an ignition circuit including a shock-responsive means, an explosive charge and a detonating means operatively connected to the shock-responsive means for igniting the explosive charge in response to a severe shock comprising: an operating mechanism for opening the ignition circuit of the motor vehicle and for actuating a fire-extinguishing unit including an operating member mounted for translation between a first position adjacent to the explosive charge and a second position remote therefrom, and adapted to be driven from its first position to its second position to open the ignition circuit and to actuate the fireextinguishing unit by the detonation of the explosive charge in response to a severe shock.
Claim 3
Dependent Claim
68 words
A fire protection device as claimed in claim 1, wherein the operating member includes a shaft having a portion which supports for movement therewith a switch normally connected in the ignition circuit, and wherein a lever for actuating the fire-extinguishing unit extends into the path of movement of the operating member so that the switch is opened and the lever is actuated by the operating member substantially simultaneously.
Claim 4
Dependent Claim
33 words
A fire protection device according to claim 2, further comprising a hollow body member, said member supporting a cartridge therein, and wherein the detonating means and the explosive are supported in the cartridge.
Claim 5
Dependent Claim
39 words
A fire protection device as claimed in claim 3, wherein the switch blade is a bridging contact, a pair of terminal contact members disposed on the body member and normally in contact with the ends of the switch blade.
Claim 6
Dependent Claim
74 words
A fire protection device as claimed in claim 4, wherein means are provided for the shaft for supporting and guiding it between the first and second position including columns depending from the body and a plate being disposed on the columns remote from the body, and wherein the shaft includes a first portion slidably engageable with the columns and a second portion extending through an aperture provided in said plate for guiding the later.
Claim 7
Dependent Claim
49 words
A fire protection device as claimed in claim 5, further comprising a cap threadedly secured to the body member for supporting a terminal electrically connected to the shock-responsive means, and the body member including a threaded portion for supporting the cartridge having a corresponding threaded portion in engagement therewith.
Claim 8
Dependent Claim
42 words
A fire protection device as claimed in claim 6, wherein a support plate is provided for supporting the fire-extinguishing unit, the body and cap, the actuating mechanism and the ignition cut out switch and an independent support for supporting the shock-responsive means.
Claim 9
Dependent Claim
35 words
A fire protection device as claimed in claim 6, wherein the fire-extinguishing unit, the body and cap, the actuating mechanism, the ignition cut out switch and the shock-responsive means are supported on a single support.
Claim 10
Dependent Claim
57 words
A fire protection device as cLaimed in claim 2, wherein the shock-responsive means is an inertia switch mounted on an insulating support, and includes a weighted contact supported a coil spring which is secured to the insulating support by a securing member and adapted to engage a conductive body disposed thereabout in response to a severe shock.
Claim 11
Dependent Claim
38 words
A fire protection device as claimed in claim 8, wherein means for adjusting the flexibility of the coil spring includes a sleeve adjustably positioned in the coil of the spring and secured in place in the securing member.
Claim 12
Dependent Claim
36 words
A fire protection device as claimed in claim 3, wherein a cover for enclosing the operating mechanism is mounted on the operating member and is in resilient engagement with the body member in the first position.
Claim 13
Dependent Claim
35 words
A fire protection device as claimed in claim 7, wherein the fire-extinguishing unit includes a cylinder having a reinforcing plate disposed thereon for supporting a securing means for mounting said unit on the support member.
