Abstract

An infant safety seat with an adjustable accommodating space includes a multi-layer cushioning insert which is detachably insertable into an infant safety seat for accommodating an infant in different stages of growth with different sizes. The multi-layer cushioning insert comprises a first cushioning part and a second cushioning part both may detachably to overlap each other and connect into the accommodating space to provide the necessary support for keeping an infant in proper postural position. The first cushioning part includes a U-shaped head cushion part, U-shaped body cushion part and U-shaped leg cushion part for restricting the side moving of the infant. Further, for accommodating a smaller infant, the second cushioning part can be detachably overlapped onto the first cushioning part for further reducing the side moving space and upright moving space of the baby in the infant safety seat.

Claims19

Dependent claims

A base retaining system with a belt tension indicator, includes a belt for securing a base to a vehicle seat, and a lock-off indicating mechanism for releasably locking the belt to the base so as to prevent the base from wobbling relative to the vehicle seat, wherein the lock-off indicating mechanism includes:

a biting compartment, formed on the base where the belt could pass thereover in a tightened condition;
a covering plate, having one end coaxial with a colored rotor and pivoted to a first end of the biting compartment, and having another end pivoted with a rotatable depressor for pressing the belt into the biting compartment when the covering plate is rotated and positioned in a closed position,
wherein the rotatable depressor has a free end, and the colored rotor is formed with an engaging slot for the free end of the rotatable depressor to be inserted therein, so as to be diable by the rotatable depressor;
and
wherein when the rotatable depressor presses the belt into the biting compartment, the free end of the rotatable depressor dials the colored rotor to rotate to reveal a selected color area;
and
a holding plate, having one end pivoted to a second end of the biting compartment, and engagable with the covering plate for holding the covering plate in the closed position so as to bite the belt in the biting compartment.

a biting compartment, formed on the base where the belt could pass thereover in a tightened condition;
a covering plate, having one end coaxial with a colored rotor and pivoted to a first end of the biting compartment, and having another end pivotally fixed to one end of a rotatable depressor;
a holding plate, having one end pivoted to a second end of the biting compartment, and engagable with the covering plate for holding the covering plate in a closed position so as to bite the belt in the biting compartment,
a resilient element for keeping the covering plate and the rotatable depressor in an opened position,
wherein when the covering plate and the rotatable depressor rotates around the colored rotor from the opened position to the closed position, the resilient element is compressed, and the covering plate and the rotatable depressor presses the belt into the biting compartment, such that a free end of the rotatable depressor dials the colored rotor to rotate to reveal a selected color area;
and
wherein the closed position is maintained by engaging the holding plate with the covering plate.
