Child safety device adaptable on a vehicle

Abstract

Child safety device able to be adapted on a vehicle. The device of the invention includes a portable element ( 2 ) fitted with a tiltable arch-shaped handle ( 4 ) and a base ( 3 ) permanently fixed on a seat of the vehicle, the portable element ( 2 ) and the base ( 3 ) being equipped with centering and positioning means and vertical locking means via the rotation of the portable element ( 2 ) with respect to the base ( 3 ). According to the invention, the vertical locking means include an anchorage piece ( 15 ) provided with at least one locking branch ( 16 ) and an opening ( 17 ) emerging into a cavity and making it possible to insert the locking branch ( 16 ) through the opening ( 17 ) according to an engaging position and then bringing the portable element ( 2 ) into a locking position via a relative rotation of the anchorage piece ( 15 ) with respect to the opening ( 17 ).

1 . Adaptable child safety device for use on a vehicle and including a portable element ( 2 ) provided with:

         2 . Device according to  claim 1 , characterised in that the anchorage piece ( 15 ) has the shape of a “T” whose upper portion constitutes two locking branches ( 16 ).  
     
     
         3 . Device according to  claim 1  or  2 , characterised in that the anchorage piece ( 15 ) is placed on the support surface ( 11 ) and the opening ( 17 ) is fitted on the bearing surface ( 13 ).  
     
     
         4 . Device according to one of  claims 1  to  3 , characterised in that the means for vertically locking the portable element ( 2 ) with respect to the base ( 3 ) further include at least one stop ( 18 ) placed on the portable element ( 2 ) and at least one tab ( 19 ) placed on the base ( 3 ), the stop ( 18 ) and the tab ( 19 ) being placed in such a way that the stop ( 18 ) is inserted under the tab ( 19 ) during rotation of the portable element ( 2 ) with respect to the base ( 3 ) in the locking position.  
     
     
         5 . Device according to one of  claims 1  to  4 , characterised in that the centering and positioning means include on the support surface ( 11 ) a centering truncated cone ( 12 ) cooperating with the bearing surface ( 13 ) placed under the portable element ( 2 ).  
     
     
         6 . Device according to one of  claims 1  to  5 , characterised in that the support surface ( 11 ) and the bearing surface ( 13 ) have shapes exhibiting a symmetry of revolution with respect to a spin axis ( 14 ) of the portable element ( 2 ) with respect to the base ( 3 ).  
     
     
         7 . Device according to one of  claims 1  to  6 , characterised in that a locking in rotation of the portable element ( 2 ) is ensured by a slanting towards the rear of the tiltable arch-shaped handle ( 4 ) on both sides of bosses ( 20 ) situated on the base ( 3 ).  
     
     
         8 . Device according to one of  claims 1  to  7 , characterised in that the portable element ( 2 ) is fitted with two lateral handles ( 22 ) to provide easy transport with studied grasping, even when the arch-shaped handle ( 4 ) is slanted.  
     
     
         9 . Device according to one of  claims 1  to  8 , characterised in that the portable element ( 2 ) includes a body for receiving a seat for a child.  
     
     
         10 . Device according to  claim 9 , characterised in that the engaging position corresponds to a position of the portable element ( 2 ) with respect to the base ( 3 ) in which the child is placed perpendicular to a driving direction of the vehicle.  
     
     
         11 . Device according to  claim 9  or  10 , characterised in that the locking position corresponds to a position of the portable element ( 2 ) with respect to the base ( 3 ) in which the child is placed parallel to a driving direction of the vehicle.
