Abstract
The invention relates to a child safety seat (100) comprising an integral harness belt (102) for restraining a child in the child safety seat (100), a belt tension monitor (106) adapted for monitoring a belt tension acting on the harness belt (102), a motorized harness belt tensioner (104) comprising a tensioning element (114) driven by an electromechanical actuator (122) and adapted for adjusting the belt tension acting on the harness belt (102), and a controller adapted for controlling the motorized harness belt tensioner (104) to adjust the belt tension to match a first predefined belt tension and for monitoring the resulting belt tension using the belt tension monitor (106).
Claims15
A child safety seat comprising:
- an integral harness belt for restraining a child in the child safety seat,
- a motorized harness belt tensioner comprising a tensioning element driven by an electro-mechanical actuator and adapted for adjusting the belt tension acting on the harness belt,
- a controller adapted for controlling the motorized harness belt tensioner to adjust the belt tension to match a first predefined belt tension, the controller being adapted for controlling the motorized harness belt tensioner to increase the belt tension from the first predefined belt tension to a second predefined belt tension upon receiving a first trigger signal indicating a potential imminent accident of a vehicle in which the child safety seat is installed.
