Child car seat inclining and swivelling between a travelling position and an installing position

Abstract

A child car seat device is provided, which includes a base intended to be fitted to a car seat and designed to accept a seat. The seat is movable in rotation in a substantially horizontal plane, so as to allow movement from a travelling position, in which said seat is orientated according to the principal axis of said vehicle, to a position for installing a child, in which said seat is turned substantially facing a door of said vehicle. The seat is also movable in inclination. The base has a part extending substantially vertically so as to lean against the backrest of said car seat, and whose upper part has a connection zone with the upper part of the backrest of said seat. In said travelling position, said inclination is obtained essentially by rotating said seat in a substantially vertical plane about a fixed point belonging, in said travelling position, to said connection zone.

1 . A child car seat device comprising a base intended to be fitted to a car seat and designed to accept a seat, said seat being movable in rotation in a substantially horizontal plane, so as to allow movement from a travelling position, in which said seat is orientated according to a principal axis of a vehicle in which the car seat device is installed, to a position for installing a child, in which said seat is turned substantially facing a door of said vehicle and said seat being movable in inclination, wherein said base comprises a part extending substantially vertically so as to lean against the backrest of said car seat, and whose upper part has a connection zone with the upper part of the backrest of said seat, in said travelling position, wherein said inclination is obtained essentially by rotating said seat in a substantially vertical plane, about a fixed point belonging, in said travelling position, to said connection zone.  
   
   
       2 . The device according to  claim 1 , wherein said seat is assembled on a single plate, which ensures both the mobility in rotation and inclination.  
   
   
       3 . The device according to  claim 2 , wherein said plate comprises at least one guiding zone substantially defining an arc of a circle, collaborating with a complementary guiding element connected to said seat.  
   
   
       4 . The device according to  claim 2 , wherein said plate bears at least a rack, defining at least two pre-set positions of inclination of said seat.  
   
   
       5 . The device according to  claim 1 , wherein said connection zone comprises at least one locking element assembled on said base or said backrest, which collaborates with at least one anchorage element assembled on the other of said base or said backrest, when said backrest is in said travelling position.  
   
   
       6 . The device according to  claim 5 , wherein said anchorage element comprises at least a rod and said locking element comprises at least a housing and/or at least a catching hook of said rod.  
   
   
       7 . The device according to  claim 5 , wherein said anchorage element is connected to return means with the tendency of returning the anchorage element to a locking position.  
   
   
       8 . The device according to  claim 7  wherein the locking element comprises means for guiding the anchorage element on said locking element when said seat moves from the installing position to the travelling position, and/or vice versa.  
   
   
       9 . The device according to  claim 8 , wherein said means for guiding act on said anchorage element by opposing a restoring force of said return means, until bringing said anchorage element into contact with said locking element.  
   
   
       10 . The device according of  claim 8 , wherein said means for guiding have a width sufficient to collaborate with said anchorage element irrespective of the inclination of said seat.  
   
   
       11 . The device according to  claim 5  and further comprising means for unlocking, allowing to positively disconnect said locking element from said anchorage element, then to move the seat from said travelling position to said installing position.  
   
   
       12 . The device according to  claim 11 , wherein said means for unlocking comprise at least a cam acting on said anchorage element so as to disengage the anchorage element from said locking element.  
   
   
       13 . The device according to  claim 11 , wherein said means for unlocking are controlled in an off-set manner, by means of a control cable.  
   
   
       14 . The device according to  claim 13 , wherein said means for unlocking are controlled by one or other of two control elements, respectively fitted on each of the sides of said seat or of said base.  
   
   
       15 . Child seat equipping the device according to  claim 1 .  
   
   
       16 . Base for device according to  claim 1.
