Example eleven:
the structure is basically the same as that of the eighth embodiment, except that: the annex is branch 8, just branch 8 with for self length adjustable's telescopic link, the upper end of branch 8 is as the stiff end, and this stiff end is articulated with the front end of girder 2, on initiative piece 4 was fixed in the fixed end of branch 8, the lower extreme of branch 8 was the end that freely stretches out and draws back, and the axial stretch of branch 8 can be followed to this end that freely stretches out and draws back.
The invention provides a car safety seat with the base, which comprises a bearing frame arranged on the base 1, wherein the rear end of the base is provided with a connecting piece used for being detachably assembled with a fixed seat on a vehicle, so that the base 1 of the child car safety seat can be well fixed on a seat on the rear row of the vehicle. The front end of the base 1 is provided with a movable main beam 2, one end of the main beam 2 is fixedly connected with the base 1, the main beam 2 can be used for installing accessories, the external accessories can be connected with a safety lock catch in a vehicle or abut against the surface in the vehicle, no matter which accessory is, the purpose of the accessory is to provide extra safety support for the front end of the base 1, and the base 1 of the automobile safety seat disclosed by the invention is more favorable for obtaining the tensile force support of a connecting piece at the rear end of the base 1 and the support of the accessories on the main beam 2 when the vehicle collides, so that the safety performance of the automobile safety seat is improved compared with the existing safety seat which is installed only through the lock catch of the connecting piece. Especially for safety seats which are partly pivotable to enable the carrier to be oriented adjustably, the support of the main beam 2 to the base 1 is more important than the tightening of the connecting members to the base 1, when the safety seat is arranged in a position in which it is adapted to a young child, with the centre of gravity of the carrier directed rearwards, because the centre of gravity of the carrier is closer to the front end of the base 1.
