Definitions

  • the present invention relates to improvements in or relating to child vehicle seats.
  • child car seats of the first stage type in which a baby is restrained in a seat which can be carried by means of an integral handle to and from the car.
  • Such seats can be used outside the car and often include rocking functionality.
  • the seats are restrained in the car using the conventional adult 3 -point seat belt.
  • Car seats of this type include a three or five point harness to restrain the child.
  • the harness must be properly tensioned to restrain the child adequately in the seat during travel.
  • the tension in the harness is often relaxed to give the baby, often sleeping, greater freedom of movement and comfort.
  • it is essential for the child's safety to re-tension the harness properly prior to re-installing the seat in the car and driving off. This requirement is all to easy for parents and carers to forget.
  • the present invention seeks to provide a vehicle seat which addresses this problem.
  • the present invention provides a demountable child vehicle seat comprising a seat body and a carrying handle, wherein the seat further comprises a child restraint harness.
  • the invention is characterised in that the vehicle seat further comprises a supplementary harness tensioning system adapted to apply tension to the harness when the seat is used in an operative configuration in a vehicle and to disapply tension when the seat is in a demounted configuration.
  • the tensioning system comprises at least one tensioning element associated with the carrying handle.
  • the tensioning element comprises a cam element associated with the carrying handle and adapted to bear against a portion of webbing of the harness.
  • the vehicle seat further comprises a seat base upon which the seat body is mountable, wherein the seat body and seat base include intercooperating tensioning elements.
  • the seat base comprises a projecting element and the seat body comprises an aperture or indent over which a portion of the webbing passes, such that upon mounting of the seat body upon the seat base, the projecting element bears against the webbing and thereby tensions the webbing.
  • the projecting element is in the form of a ridged projection.
  • the seat base further comprises belt retaining means adapted to receive and be retained, in use, by a seat belt restraint of the vehicle.
  • Figure 1 is a schematic side, part sectional, view of a first embodiment of a seat in accordance with the present invention in a demounted configuration
  • Figure 2 is a schematic side, part sectional, view of the embodiment of Figure 1 in a mounted configuration upon a vehicle seat;
  • Figure 3 is a schematic side, part sectional, view of a second embodiment of a seat in accordance with the present invention in a demounted configuration
  • Figure 4 is a schematic side, part sectional, view of the embodiment of Figure 3 in a mounted configuration.
  • FIG. 1 there is illustrated an embodiment of a car seat 10 in accordance with the present invention.
  • the seat is generally conventional in construction and includes a seat body 11 providing a generally bucket-shaped seat surface 12.
  • a carrying handle 13 is pivotally mounted upon the seat body 11 and is moveable between a carrying position ( Figure 1) and a travelling position ( Figure 2).
  • the handle 13 will be placed in the stowed position when the seat is installed in a vehicle such as a car whereupon the seat body sits upon the seat surface 14 of the car and the carrying handle bears against the surface of the back 15 of the car seat, thereby providing a bracing function.
  • the car seat includes a child restraint harness 20 generally of the 3-point or 5-point type.
  • shoulder webbing portions 21 pass though apertures in the seat adjacent (in use) the child's shoulders and then down over the shoulders to act as shoulder restraints.
  • the shoulder webbing portions terminate in buckle elements 22 which are received by and retained within a buckle 23 mounted one and end of a crotch webbing portion 24 which then passes through an aperture in the seat between the child's legs and is retained therein.
  • the shoulder webbing portions typically include length adjustment means which, by adjusting the length of the webbing over the child's shoulders, provide a primary tensioning system.
  • the shoulder webbing portions are coupled to or form a part of a tensioning belt 25.
  • Tensioning belt 25 passes underneath the seat and through an aperture in a forward portion of the seat where it is retained by a clamp element 30.
  • Primary tensioning arrangements of this type are known from the field of car seats for older children.
  • the harness 20 is tensioned by pulling on tensioning belt 25 and is retained at the desired tension by clamp element 30.
  • Tension in the harness is relaxed by releasing clamp element 30 and pulling on the shoulder webbing portions 21.
  • a supplementary tensioning system is provided.
  • the supplementary tensioning system is formed by a cam surface 31 associated with carrying handle 13 and which bears against tensioning belt 25 as handle 13 is moved from the carrying position ( Figure 1) to the travelling position ( Figure 2).
  • the cam surface 31 is formed by a cam element mounted upon a beam passing under the seat, the beam being operatively coupled to the carrying handle 13.
  • the cam surface 31 bears against the tensioning belt 25
  • the belt 25 is pulled into a more tensioned state ( Figure 2).
  • the child is thus better restrained by the harness 20, even if the parent has forgotten to tension the harness using the primary tensioning system.
  • the car seat 40 comprises a seat unit 41 and a base unit 42.
  • the base unit sits upon the surface of the seat of the car.
  • the seat unit 41 is of generally conventional construction and includes a generally bucket shaped seat 42, a pivotable carrying handle 43 and a harness 44 of the same general construction as described above for the first embodiment, comprising a shoulder harness arrangement 45 engaging a buckle 46 on a crotch strap 47 and including a tensioning belt 50, retainable in a predetermined position by means of clamp element 51.
  • Seat unit 41 and base unit 42 include intercooperating tensioning elements to form the supplementary tensioning system.
  • the base unit 42 includes a projection 52 which mates with an aperture or recess 53 formed in an underside surface of the seat unit 41.
  • Projection 52 and recess 53 are located on their respective components in a position such that as the components are brought together, projection 52 bears against the tensioning belt 50, pushing it into recess 53 and thereby increasing the tension of the harness 44.
  • the intercooperating tensioning elements are located towards an upper, or head, end of the seat. In alternative embodiments, these elements are located in any suitable position. For example, location in the region of the feet end of the seat is equally suitable.
  • the base unit 42 includes belt retaining elements (not shown) to receive and thereby be retained in place by webbing of the conventional three point vehicle seat belt. Accordingly, the base unit 42 is retained in position in the car as the seat unit 41 itself is removed.
  • the seat unit 41 includes the belt retaining elements such that, in use, the vehicle's seat belt retains both the seat unit 41 and the base unit 42.
