An engaging member guides and supports the top tether to restrain both seat and base, reducing impact movement and head displacement.
Slit-divided buffer blocks let a child seat cushion deform under impact, dispersing collision force while preserving normal support.
A deformable recline foot absorbs crash energy at lower force than the rigid seat structure, improving child seat protection across reclined positions.
A retainer latch and release actuator let a juvenile seat rotate yet stay securely locked to the base for easier installation and removal.
An engaging member guides and supports the top tether to reduce seat-base movement and child head displacement during impact.
A hinged dual-slider carrier structure adjusts the backrest-leg angle to fit different baby postures while keeping support stable.
A retractable pin-and-hole backrest lock with elastic recovery makes child seat attachment and detachment simpler without sacrificing secure engagement.
A pivoting side-impact block uses elastic cantilever locking to simplify child seat protection while securing both extended and retracted positions.
