Abstract: A connecting device comprising, a piercing housing for receiving the neck of a gas cylinder with a top surface comprising a gas outlet the piercing housing is defined by an opening, side wall and a bottom wall a piercing member arranged in the piercing housing for piercing the gas outlet of the gas cylinder a container defining a space for retaining the gas cylinder a protection cap being provided in the piercing housing which encloses the piercing member partially and can be pushed axially relative to the piercing member, wherein the axial direction coincides with the axis of the gas cylinder, wherein a male portion is provided on the protection cap for connecting the protection cap with the neck of the gas cylinder on which a female portion is present, wherein the female portion has a corresponding shape for being inserted in the male portion, the male portion and the female portion are fitted with each other when a correct position is achieved so that after the fitting the both portions cannot be rotate

Abstract: A child safety seat having a seat, a backrest, and a belt device for buckling a child therein. The belt device includes a shoulder belt routed through an opening in the backrest. The opening includes a longitudinal slot extending in a longitudinal direction of the backrest in a reclining element and a belt slot in a belt guide piece. The guide piece is movable along the reclining element to adapt the position of the belt slot to the child's body. The guide piece detachably connects to the reclining element via a locking device having a locking element pretensioned by a reset force. An actuating element on the reclining element applies tensile force to the tensioning element, counter to the reset force. This moves the locking element into a release setting, thus releasing the locking device and displacing the guide piece along the longitudinal direction of the backrest.

Abstract: A child seat having a seat surface, a backrest, and a headrest. The headrest has first and second side pieces adjustable in their spacing relative to one another in a substantially horizontal direction. The side pieces are positionable in at least two different positions with respect to one another and to the backrest by means of a spacing adjustment device. The spacing adjustment device includes a gear mechanism having a first gear element rotatable around a rotational axis and a second and third gear element, each movable in a translational manner. The second gear element connects to the first side piece and the third gear element connects to the second side piece. The first gear element couples to the second and third gear elements such that, by means of rotation of the first gear element, opposite and simultaneous translational motions of the second and third gear elements are effected.
