Inflector with clamping device for a safety belt in motor vehicles

Claim 1

An apparatus for use in a motor vehicle to clamp a safety belt, said apparatus comprising a stationary clamp member, a movable clamp member which cooperates with said stationary clamp member to define space through which the belt passes, a movable slide member, a deflector member connected to said slide member and having a surface across which the safety belt extends between said deflector and slide members, said movable clamp member being movable toward said stationary clamp member by said slide member under the influence of force applied against said deflector member by the belt to thereby clamp the belt between said movable and stationary clamp members.

Claim 2

An apparatus for use in a motor vehicle to clamp a safety belt, said apparatus comprising a stationary clamp member, a movable clamp member which cooperates with said stationary clamp member to define space through which the belt passes, a movable slide member, a deflector member connected to said slide member and having a surface across which the safety belt extends between said deflector and slide members, said movable clamp member being movable toward said stationary clamp member by said slide member under the influence of force applied against said deflector member by the belt to thereby clamp the belt between said movable and stationary clamp members.

Claim 7

An apparatus for use in a motor vehicle to clamp a safety belt, said apparatus comprising a clamp member, a roller having an outer side surface which cooperates with said clamp member to define a space through which the belt passes, means for supporting said roller for pivotal movement about an axis which is offset form the central axis of the roller, spring means for biasing said roller to a retracted position spaced from said clamp member, a movable slide member, a deflector member connected with said slide member and having a surface across which the belt extends, track means for guiding movement of said slide member toward said roller under the influence of force applied to said deflector member by the belt, said roller being pivotal about its offset axis against the influence of said spring means by movement of said slide member along said track means toward said roller to thereby clamp the belt between said roller and clamp member.

Claim 8

An apparatus for use in a motor vehicle to clamp a safety belt, said apparatus comprising a clamp member, a roller having an outer side surface which cooperates with said clamp member to define a space through which the belt passes, means for supporting said roller for pivotal movement about an axis which is offset form the central axis of the roller, spring means for biasing said roller to a retracted position spaced from said clamp member, a movable slide member, a deflector member connected with said slide member and having a surface across which the belt extends, track means for guiding movement of said slide member toward said roller under the influence of force applied to said deflector member by the belt, said roller being pivotal about its offset axis against the influence of said spring means by movement of said slide member along said track means toward said roller to thereby clamp the belt between said roller and clamp member.

Claim 10

An apparatus for clamping a safety belt which extends toward and passes over an occupant seated in a vehicle to restrain the occupant from moving away from the seat upon a sudden change in acceleration of the vehicle, comprising a safety belt extending across an occupant of the vehicle and having one end attached to an automatic roll-up device mounted on the vehicle and the other end detachably connected to a belt lock, a deflector device having a deflector member with a cambered surface which is partly wrapped around by said belt, a slider mounted on the vehicle and slideable back and forth, said deflector member being mounted on said slider and slideable therewith, a clamping device having a stationary clamping jaw normally spaced from a swivelable clamping jaw to permit said belt to pass therebetween and to move freely relative to said deflector member, spring means urging said swivelable clamping jaw away from said stationary clamping jaw, said slider being disposed adjacent said swivelable clamping jaw, said slider and connector member being movable upon an increase in belt pull sufficient to overcome said urging of the spring means to cause the swivelable clamping jaw to swivel and move toward the stationary clamping jaw to clamp the belt between said stationary and movable clamping jaws.

Claim 11

An apparatus for clamping a safety belt which extends toward and passes over an occupant seated in a vehicle to restrain the occupant from moving away from the seat upon a sudden change in acceleration of the vehicle, comprising a safety belt extending across an occupant of the vehicle and having one end attached to an automatic roll-up device mounted on the vehicle and the other end detachably connected to a belt lock, a deflector device having a deflector member with a cambered surface which is partly wrapped around by said belt, a slider mounted on the vehicle and slideable back and forth, said deflector member being mounted on said slider and slideable therewith, a clamping device having a stationary clamping jaw normally spaced from a swivelable clamping jaw to permit said belt to pass therebetween and to move freely relative to said deflector member, spring means urging said swivelable clamping jaw away from said stationary clamping jaw, said slider being disposed adjacent said swivelable clamping jaw, said slider and connector member being movable upon an increase in belt pull sufficient to overcome said urging of the spring means to cause the swivelable clamping jaw to swivel and move toward the stationary clamping jaw to clamp the belt between said stationary and movable clamping jaws.
