Abstract
The invention relates to a child safety seat for attaching to a motor vehicle seat, comprising a seat region, a back portion, an impact shield, the impact shield comprising an integrated airbag and/or an airbag being provided in the seat region, an acceleration-sensing device for sensing an acceleration of the child safety seat, and a control device, which is configured in such a way that the airbag is deployed on the basis of an acceleration sensed by the acceleration-sensing device.
Claims15
A child safety seat for attaching to a motor vehicle seat, comprising:
- a seat region,
- a back portion,
- an anchoring device,
- an acceleration sensor configured for sensing an acceleration of the child safety seat, wherein the acceleration sensor is affixed at a location in or on the anchoring device,
- a control device which is not provided at a location in or on the anchoring device but is part of the child safety seat, wherein the control device is connected to the acceleration sensor, and:
- an impact shield for restraining a torso of a child and a shield positioning apparatus configured for positioning the impact shield, wherein the control device is configured to activate the shield positioning apparatus to position the impact shield in response to an acceleration sensed by the acceleration sensor and exceeding a predetermined acceleration, wherein by being positioned the impact shield is shifted towards a child occupant sitting in the child safety seat and towards one or both of the seat region and the back portion;
- and
- wherein the impact shield and a main body of the child safety seat define a space for receiving a torso of the child.
5 more elements
A method for operating a child safety seat attached to a motor vehicle seat, the method comprising:
- arranging a seat region of the child safety seat and a back portion of the child safety seat relative to the motor vehicle seat;
- configuring an acceleration sensor to sense acceleration of the safety seat, wherein the acceleration sensor is affixed at a location in or on an anchoring device of the child safety seat;
- sensing acceleration using the acceleration sensor and upon detecting a predetermined acceleration, activating the child safety seat by means of a control device, wherein activating the child safety seat includes at least one of:
- using a positioning apparatus configured to position at least one of an impact shield of the child safety seat for restraining a torso of a child and an anchor of the child safety seat, wherein positioning of the impact shield includes shifting the impact shield towards a child occupant sitting in the child safety seat and towards one or both of the seat region and the back portion, and wherein positioning of the anchor includes positioning the anchor relative to the motor vehicle seat;
- and
- using a belt tensioner apparatus configured to tighten a belt system of the child safety seat, and
- wherein the control device is not provided at a location in or on the anchoring device but is part of the child safety seat, wherein the control device is connected to the acceleration sensor.

A child safety seat for attaching to a motor vehicle seat, comprising:
- a seat region,
- a back portion,
- a control device,
- an acceleration sensor configured for sensing an acceleration of the child safety seat, and
- at least one of:
- a seat anchor system and a second positioning apparatus, wherein the control device is configured to activate the second positioning apparatus to position the seat anchor system in response to an acceleration sensed by the acceleration sensor and exceeding a predetermined acceleration, and,
- a belt system and a first positioning apparatus, wherein the control device is configured to activate the first positioning apparatus to tighten the belt system in response to an acceleration sensed by the acceleration sensor and exceeding a predetermined acceleration, the belt system including a lap belt and a shoulder belt connected by a coupling element, and, wherein the child safety seat comprises an anchoring device, wherein the acceleration sensor is affixed at a location in or on the anchoring device, wherein the control device is not provided at a location in or on the anchoring device but is part of the child safety seat.
