Abstract
Abstract A slide fitting for a safety belt, comprising a cross bar movable between a belt locking and a belt releasing position and an electromagnetic coil and armature combination formed on a hinged arm to effect sliding movement of the cross bar, by means of at least one link connected between the arm and the frame, the armature being carried by the arm and the coil by the frame. Switch means enable the cross bar to be moved to its first belt locking position by energizing of the coil when desired.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A lockable slide fitting for use in a vehicle safety belt system of the ''''lap and diagonal'''' type having three points of attachment and comprising a fixed reel device for one end of a shoulder strap which strap may slide through the lockable slide fitting before passing diagonally across the chest of the vehicle occupant to be anchored by its other end in the vicinity of the floor, the said lockable slide fitting comprising a frame, means for attaching the frame to a component of the body of the vehicle, means including a movable cross bar slidably mounted in the frame for movement between a first position in which the strap is locked and a second position and over which the strap may pass, an arm hinged to the frame of the fitting, at least one rod connecting said cross bar to said arm, an armature of ferromagnetic material supported by said arm, a coil carried fixedly by said frame and co-operating with the armature, and means for connecting said coil to an electric circuit to energize the coil.
Claim 2
Dependent Claim
179 words
A lockable slide fitting for use in a vehicle safety belt system of the ''''lap and diagonal'''' type having three points of attachment and comprising a fixed reel device for one end of a shoulder strap which strap may slide through the lockable slide fitting before passing diagonally across the chest of the vehicle occupant to be anchored by its other end in the vicinity of the floor, the said lockable slide fitting comprising a frame, means for attaching the frame to a component of the body of the vehicle, means including a movable cross bar slidably mounted in the frame for movement between a first position in which the strap is locked and a second position and over which the strap may pass, an arm hinged to the frame of the fitting, at least one rod connecting said cross bar to said arm, an armature of ferromagnetic material supported by said arm, a coil carried fixedly by said frame and co-operating with the armature, and means for connecting said coil to an electric circuit to energize the coil.
Claim 3
Dependent Claim
58 words
A slide fitting according to claim 1, and said second mentioned means includes a fixed cross bar firmly attached to the fRame of the fitting to co-operate with the movable cross bar such that the strap is locked between the movable cross bar and the fixed cross bar when said movable cross bar is in its first position.
Claim 4
Dependent Claim
27 words
A slide fitting according to claim 1, and including an energy absorbing device connected between said fitting and said means for attaching the frame to a vehicle.
Claim 5
Dependent Claim
83 words
A slide fitting according to claim 3, wherein said energy absorbing device comprises a clock spring having a radially inner end located within said frame and a tangentially extending end connected to said attaching means, means defining a slit in said frame through which said tangentially extending end passes, an axle secured to said radially inner end and loosely received within said frame, and a knife to engage said spring as said tangentially extending end is drawn through said slit in the frame.
Claim 6
Dependent Claim
79 words
A slide fitting of claim 1 in combination with means, including: the safety belt with a shoulder strap and the lap strap, a reel device connected to one end of said shoulder strap and the slide fitting secured to a side wall of the vehicle with said shoulder strap slidably extending therethrough, and an electric circuit connected to said slide fitting, said circuit including a source of current and switch means for energizing said coil to repel said armature.
Claim 7
Dependent Claim
21 words
A slide fitting, safety belt, and reel device combination according to claim 5, wherein said switch means comprise an inertia switch.
Claim 8
Dependent Claim
34 words
A slide fitting, safety belt, and reel device combination according to claim 5, wherein said switch means comprise a switch connected to a vehicle brake pedal to be closed when said pedal is operated.
Claim 9
Dependent Claim
113 words
A fitting for a vehicle safety belt system comprising a frame for locking engagement with a safety belt, and energy absorbing means consisting of a clock spring having a radially inner end located with said frame and a tangentially extending end located outside said frame, means on said frame defining a slit to receive said tangentially extending end for sliding movement therethrough, an axle fastened to said radially inner end of the spring and received loosely in said frame, means secured to the tangentially extending end for attaching to a vehicle body, and knife means on said frame for engaging said clock spring as said tangentially extending end is pulled through said slit.
Claim 10
Dependent Claim
113 words
A fitting for a vehicle safety belt system comprising a frame for locking engagement with a safety belt, and energy absorbing means consisting of a clock spring having a radially inner end located with said frame and a tangentially extending end located outside said frame, means on said frame defining a slit to receive said tangentially extending end for sliding movement therethrough, an axle fastened to said radially inner end of the spring and received loosely in said frame, means secured to the tangentially extending end for attaching to a vehicle body, and knife means on said frame for engaging said clock spring as said tangentially extending end is pulled through said slit.
