Abstract
Abstract The steering wheel column and/or the bearing for the steering wheel column in a motor vehicle is pushed or pulled away from a position in front of the driver in the event of a head-on collision whose intensity exceeds a preselected minimum value. The displacing unit which is activated in the event of head-on collision of preselected minimum intensity (e.g., a collision which causes the engine block and/or the transmission case to move rearwardly with reference to the frame of the motor vehicle) can entrain the steering wheel column and/or the bearing for the steering wheel column by way of a carrier which is pivotably mounted adjacent the steering wheel column or its bearing and has one or more projections with cutting edges penetrating into the steering wheel column and/or bearing in response to activation of the displacing unit. Each projection can include a cylindrical portion which extends at an oblique angle from a side of the carrier and whose axis preferably makes an acute angle with an adjacent surface of the steering wheel column or its bearing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
Apparatus for reducing the likelihood of injury to a driver of a motor vehicle of the type wherein a column member for a steering wheel is installed in a bearing member and at least one of said members is movable away from a position in front of the driver of the motor vehicle by a displacing unit which is responsive to a head-on collision whose intensity exceeds a predetermined minimum value, comprising a carrier uncoupled from and adjacent to said at least one of said members and connected with said unit to be displaced in the event of a collision of said intensity; and means for coupling said carrier to said at least one of said members in response to displacement of said carrier by said unit so that said at least one of said members is moved away from said position in front of the driver of the motor vehicle, said coupling means comprises at least one projection which establishes a form locking connection between said carrier and said at least one of said members in response to displacement of said carrier by said unit.
Claim 2
Dependent Claim
186 words
Apparatus for reducing the likelihood of injury to a driver of a motor vehicle of the type wherein a column member for a steering wheel is installed in a bearing member and at least one of said members is movable away from a position in front of the driver of the motor vehicle by a displacing unit which is responsive to a head-on collision whose intensity exceeds a predetermined minimum value, comprising a carrier uncoupled from and adjacent to said at least one of said members and connected with said unit to be displaced in the event of a collision of said intensity; and means for coupling said carrier to said at least one of said members in response to displacement of said carrier by said unit so that said at least one of said members is moved away from said position in front of the driver of the motor vehicle, said coupling means comprises at least one projection which establishes a form locking connection between said carrier and said at least one of said members in response to displacement of said carrier by said unit.
Claim 3
Dependent Claim
35 words
The apparatus of claim 1, wherein said at least one projection has a cutting edge which penetrates into said at least one of said members in response to displacement of said carrier by said unit.
Claim 4
Dependent Claim
26 words
The apparatus of claim 2, wherein said at least one projection has a substantially cylindrical portion and said cutting edge is provided on said cylindrical portion.
Claim 5
Dependent Claim
36 words
The apparatus of claim 3, wherein said cylindrical portion has an axis and said at least one of said members has a surface adjacent to said cylindrical portion and making an oblique angle with said axis.
Claim 6
Dependent Claim
12 words
The apparatus of claim 4, wherein said angle is an acute angle.
Claim 7
Dependent Claim
37 words
The apparatus of claim 5, wherein said carrier has a side adjacent to said at least one of said members, said cylindrical portion extending from said side and said axis making with said side an oblique angle.
Claim 8
Dependent Claim
14 words
The apparatus of claim 1, wherein said unit comprises means for pulling said carrier.
Claim 9
Dependent Claim
168 words
Apparatus for reducing the likelihood of injury to a driver of a motor vehicle of the type wherein a column member for a steering wheel is installed in a bearing member and at least one of said members is movable away from a position in front of the driver of the motor vehicle by a displacing unit which is responsive to a head-on collision whose intensity exceeds a predetermined minimum value, comprising a carrier uncoupled from and adjacent to said at least one of said members and connected with said unit to be displaced in the event of a collision of said intensity; and means for coupling said carrier to said at least one of said members in response to displacement of said carrier by said unit so that said at least one of said members is moved away from said position in front of the driver of the motor vehicle, said carrier is pivotable relative to said at least one of said members about a predetermined axis.
Claim 10
Dependent Claim
168 words
Apparatus for reducing the likelihood of injury to a driver of a motor vehicle of the type wherein a column member for a steering wheel is installed in a bearing member and at least one of said members is movable away from a position in front of the driver of the motor vehicle by a displacing unit which is responsive to a head-on collision whose intensity exceeds a predetermined minimum value, comprising a carrier uncoupled from and adjacent to said at least one of said members and connected with said unit to be displaced in the event of a collision of said intensity; and means for coupling said carrier to said at least one of said members in response to displacement of said carrier by said unit so that said at least one of said members is moved away from said position in front of the driver of the motor vehicle, said carrier is pivotable relative to said at least one of said members about a predetermined axis.
