Abstract
Abstract This disclosure relates to a safety alarm device for warning a vehicle driver against states of drowsiness, which comprises a tubular sensing member arranged along the rim of a vehicle steering wheel, said sensing member being arranged to determine, according to the pressure with which it is actuated, a delay for a delay device, which, if it is not recharged before the end of such delay, actuates an acoustic alarm device, said sensing member being arranged to act on said delay device in substantially only dynamic manner.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
187 words
A safety alarm device for warning a vehicle driver against states of drowsiness including a sensing member arranged along the rim of a vehicle steering wheel, a pneumatic delaying device arranged for actuation of an acoustic signalling device, a pipe connecting said sensing member with said delaying device, said sensing member being at intervals actuated by the driver in order to send a pulse of air to said delaying device, wherein according to the improvement said delaying device comprises a rigid body means defining a cavity in said body, a duct connecting said cavity with said pipe, a cap member for closing said cavity, contact members for actuating said acoustic signalling device, said contact member being closed by the cap member according to the pressure in said cavity, a discharge opening for the air contained in said cavity, adjustment means for adjusting the wideness of said discharge opening and wherein the delaying device further comprises a first valve arranged to close said duct and to open it towards said cavity and a second valve connecting said duct with the surrounding atmosphere and opening towards said sensing member.
Claim 2
Dependent Claim
187 words
A safety alarm device for warning a vehicle driver against states of drowsiness including a sensing member arranged along the rim of a vehicle steering wheel, a pneumatic delaying device arranged for actuation of an acoustic signalling device, a pipe connecting said sensing member with said delaying device, said sensing member being at intervals actuated by the driver in order to send a pulse of air to said delaying device, wherein according to the improvement said delaying device comprises a rigid body means defining a cavity in said body, a duct connecting said cavity with said pipe, a cap member for closing said cavity, contact members for actuating said acoustic signalling device, said contact member being closed by the cap member according to the pressure in said cavity, a discharge opening for the air contained in said cavity, adjustment means for adjusting the wideness of said discharge opening and wherein the delaying device further comprises a first valve arranged to close said duct and to open it towards said cavity and a second valve connecting said duct with the surrounding atmosphere and opening towards said sensing member.
Claim 3
Dependent Claim
73 words
A safety alarm device as claimed in claim 1, wherein said contact members comprise a pair of flat springs arranged on opposite sides of said rigid body, one end of each of said flat springs normally being in contact with said cap member, lugs provided on said flat springs and arranged to come into mutual contact and actuate said acoustic device when the pressure in said cap member drops below a predetermined level.
Claim 4
Dependent Claim
46 words
A safety alarm device as claimed in claim 1, wherein each of said valve members comprises a cylindrical cavity provided in said rigid body and in communication with said duct, an airtight flexible tube which is slit along a generatrix and arranged in said cylindrical cavity.
Claim 5
Dependent Claim
41 words
A safety alarm device as claimed in claim 1, wherein said sensing member comprises a tube connected with said pipe and extending along the rim of the steering wheel and a flexible sheath member for securing said tube to said rim.
Claim 6
Dependent Claim
70 words
A safety alarm device as claimed in claim 1 wherein said acoustic signalling device comprises a case secured to the vehicle steering wheel and containing said delaying device, an electromagnet having a core arranged in said case and a battery arranged in said case to supply electric energy to said electromagnet, the core having a striker acting on the case, a switch for the deactuation of the acoustic signalling device.
