Abstract: A child safety seat has a seat body, a support structure, a first releasable coupling for connecting the support structure to a motor vehicle and a second releasable coupling for connecting the seat body to the support structure. The support structure includes an upwardly facing abutment surface positioned above the seat portion of an adult vehicle seat and in front of the backrest portion thereof, when the first coupling is engaged. The second coupling is arranged to hold the seat body in rigid abutment with the abutment surface on the support structure either so that the seat body is facing forwardly in the vehicle or so that the seat body is facing rearwardly in the vehicle.

Abstract: A child safety seat for use in a vehicle comprises a seat body having a seat portion and a backrest portion. In order to connect the seat body to a motor vehicle, a pair of attachment buckles are mounted by rigid links on opposite sides of the seat body for movement between first and second positions. In the first position, the buckles project rearwardly so as to be engageable with two anchorage units which are rigidly fixed to the vehicle body so as to be accessible between the seat portion and the backrest portion of the vehicle seat. In the second position, the buckles provide support for guides for an adult seat belt.

Abstract: A child safety seat for use in a vehicle, comprising a seat body (10), and two S-shaped coupling arms (36, 38), each of which is pivotally mounted at one end (46, 48) to the seat body (10) below the front thereof and has a front releasable fastener (58, 60) on its other end (54, 56) for attachment to a front anchorage unit located below the front edge of a vehicle seat (18). The coupling arm (36, 38) is so shaped that an intermediate portion (40, 42) thereof is located in front of both ends (46, 48; 54, 56) thereof when the front releasable fastener (58, 60) is engaged with the front anchorage unit, so as to extend round the front edge of the vehicle seat (18).

Abstract: A forward facing child safety seat has a seat body, and a base portion adapted to rest on a motor vehicle seat and to be secured in position on the vehicle seat by means of an adult lap belt which passes between the seated occupant of the child seat and the adult seat-back. The base portion has a rear projection adapted to extend towards the vehicle seat-back above the level of the vehicle seat and two side projections extending upwardly and rearwardly from the sides of the base portion so as to define respective slots with the side edges of the rearwardly projecting portion, each side projection having an upper surface above the level of the rear projection.

Abstract: A child safety harness has a pair of lap straps and a pair of shoulder straps interconnected by an impact pad which comprises an upper portion and a lower portion. Coupling means connects the upper portion to the lower portion in a plurality of alternative mutually overlapping positions so as to vary the distance between the upper edge of the upper portion and the lower edge of the lower portion.

Abstract: A child's safety seat comprises a seat body having a seat portion, a back rest and vertically extending side walls projecting forwardly from the side edges of the back rest. First and second guide means adjacent to the junction between the seat portion and the back rest for serve to locate a lap portion of an adult seat belt. A head rest is mounted on the back rest by means permitting adjustment of the distance between the head rest and the seat portion. Third guide means is positioned so as to guide a shoulder portion of an adult belt between the back rest and the head rest.

Abstract: A child's seat for a motor vehicle comprises a back portion and a harness including two shoulder straps each of which projects through a respective opening in the back portion. Each opening is formed by the interaction of an elongate slot formed in the back portion and extending over the range of desired positions for the opening, with a horizontal slot in a carriage mounted on the rear side of the back portion for vertical sliding movement relative thereto. Manually operable control means is arranged to vary the position of the carriage relative to the back portion.

Abstract: A safety device for enabling a child to use an adult vehicle safety belt of the type having a shoulder strap and a lap strap consists of a cushion (50) having a respective belt retainer (54, 56) on each side thereof, under which the lap strap of the adult safety belt engages.

In use, the belt guide connector slidably receives the shoulder strap of the adult belt so that the shoulder strap extends in front of, and the auxiliary strap extends behind the child's torso with the belt guide connector located above the child's shoulder.

Abstract: A buckle for a safety harness consists of two identical parts. Each part comprises a plate 10 having a D-shaped aperture 12 in one end, for receiving a harness, and a portion 14 at the other end folded at right angles to the rest of the plate 10 along an oblique fold line 16. A slot 18 extends half way along the fold line 16. A second plate 20 has a tab 22 welded to the portion 14 of the plate 10 at the side thereof adjacent to the slot 18. The two parts interlock with the upstanding portions 14 and 22 of one part projecting through the slot 18 in the other and vice versa. Tension applied to a harness connected to the apertures 12 tends to draw the ends 24 of the slots 18 into abutment with each other.

Abstract: A safety seat for a vehicle of the type comprising a shell 10 forming a seat portion 12 a back portion 14 and two side portions 16 and 18, which are covered by a fabric seat cover 50, is made adjustable in width by providing a plurality of filler strips 54, 56 which fit between the cover 50 and the side portions 16 and 18 of the shell so as to adjust the interior width of the seat.
