Claim 3

A fitment as set forth in claim 1, wherein said attachment means comprise two separate pins, each pin being connected to both said brake shoe means and one of said links, and each pin being disposed in a respective one of said elongate openings.

Claim 4

A fitment as set forth in claim 1, wherein said second actuating means means for driving the brake shoe means into said first position comprise electromagnetic control means which consist of an electrically conductive coil fixed to said fitment body, an armature fixed to said movable brake shoe means, and means for energising said coil to move said armature.

Claim 5

A sliding fitment for a safety belt comprising two anchorage points, a device for the elastic drawback of the belt at one anchorage point, a fitment body, a belt slidably mounted in the fitment body, means comprising a brake shoe for clamping said belt into position under the action of a brake shoe and an electro-magnetic means for moving the brake shoe into its clamping position, at least one pair of connecting links connected to the shoe and to the body mounting the brake shoe in the fitment body, one of the ends of said connecting links being secured externally of the body to a cross-tie on which the belt comes to rest when coming out of the body, a frame integral with said body and having elongated openings therein, said cross-tie being mounted for sliding in the elongate openings, said body having elongated openings therein adjacent the opposite ends of the links, shafts slidably disposed through the elongated openings in the body secured at one end to a link and at the other end to the brake shoe.

Claim 6

A sliding fitment for a safety belt comprising two anchorage points, a device for the elastic drawback of the belt at one anchorage point, a fitment body, a belt slidably mounted in the fitment body, means comprising a brake shoe for clamping said belt into position under the action of a brake shoe and an electro-magnetic means for moving the brake shoe into its clamping position, at least one pair of connecting links connected to the shoe and to the body mounting the brake shoe in the fitment body, one of the ends of said connecting links being secured externally of the body to a cross-tie on which the belt comes to rest when coming out of the body, a frame integral with said body and having elongated openings therein, said cross-tie being mounted for sliding in the elongate openings, said body having elongated openings therein adjacent the opposite ends of the links, shafts slidably disposed through the elongated openings in the body secured at one end to a link and at the other end to the brake shoe.

Claim 7

The sliding fitment of claim 4, characterized in that the electro-magnetic control means are constituted by a coil which is integral with the fitment body and which cooperates with a mobile armature, which is integral with the brake shoe.

Claim 8

A safety belt assembly for a vehicle comprising a means for coiling one end of a belt, said coiling means being fixed to a vehicle adjacent to one side of a seat in the vehicle, means adjacent to an opposite side of the seat for detachably securing an opposite end of the belt to the vehicle, and a belt guide and support means disposed between the coiling means and detachably securing means and fixed to the vehicle at a point elevated above the shoulders of an occupant sitting on said seat whereby a belt passing therethrough and secured on said coiling means and to said detachably securing means will cross diagonally from the occupant''s shoulder across his body to the detachably securing means, said belt guide and support means comprising a slot and associated exit opening for said belt, a braking means disposed in the said belt guide and support means facing said slot, electro-magnetic means for moving the braking means towards and from the slot, a pair of sprocket brackets fixed externally to the belt guide and support means below the exit opening and having elongated slots therein, a pair of linkage members disposed adjacent to and within the space between the said brackets; a cross-tie member disposed across the space between the linkage members, projecting through the said elongated openings and secured at its ends to the linkage members and means for securing said linkage members to the braking means for movement therewith, and a belt coiled at one end about the coiling means, threaded through the slot and exit opening, between the cross-tie member and the belt guide and supporting means and detachably secured at its other end to said detachably securIng means, whereby upon the application of tension on the strap the cross-tie is moved away from the guide and support means in said bracket slots and the braking means is moved towards the slot in the guide and support means and into braking engagement with the belt therein.

Claim 9

A safety belt assembly for a vehicle comprising a means for coiling one end of a belt, said coiling means being fixed to a vehicle adjacent to one side of a seat in the vehicle, means adjacent to an opposite side of the seat for detachably securing an opposite end of the belt to the vehicle, and a belt guide and support means disposed between the coiling means and detachably securing means and fixed to the vehicle at a point elevated above the shoulders of an occupant sitting on said seat whereby a belt passing therethrough and secured on said coiling means and to said detachably securing means will cross diagonally from the occupant''s shoulder across his body to the detachably securing means, said belt guide and support means comprising a slot and associated exit opening for said belt, a braking means disposed in the said belt guide and support means facing said slot, electro-magnetic means for moving the braking means towards and from the slot, a pair of sprocket brackets fixed externally to the belt guide and support means below the exit opening and having elongated slots therein, a pair of linkage members disposed adjacent to and within the space between the said brackets; a cross-tie member disposed across the space between the linkage members, projecting through the said elongated openings and secured at its ends to the linkage members and means for securing said linkage members to the braking means for movement therewith, and a belt coiled at one end about the coiling means, threaded through the slot and exit opening, between the cross-tie member and the belt guide and supporting means and detachably secured at its other end to said detachably securIng means, whereby upon the application of tension on the strap the cross-tie is moved away from the guide and support means in said bracket slots and the braking means is moved towards the slot in the guide and support means and into braking engagement with the belt therein.
