Publication number: 20170341541Abstract: Provided is a seat for infants and toddlers, which has at least one seat lower part and a seat back part, wherein a seat element and a backrest element are applied on the seat lower part and on the seat back part respectively, in a moveable manner and connected to one another. At least the backrest element is flexibly designed and is arranged at a distance from the seat back part, wherein the backrest element can be moved in the event of an influence of an impulse energy by the body of a child. At least one damping device allows a movement of the backrest element from a determined impulse energy, by which means the distance between the backrest element and the seat back part is reduced and a movement of the seat element occurs with respect to the seat lower part.Type: ApplicationFiled: December 18, 2015Publication date: November 30, 2017Inventor: Jan-Stefan Wuerstl

Patent number: 9056567Abstract: A seat element and a backrest element are integrated in a baby carrier in the form of a bucket seat, such that the angle of inclination can be adjusted. A carrying handle is pivotally and lockably mounted on the lateral walls such that the handle substantially lies on the center of gravity axis of the baby carrier. The outer upper end of the seat element or the backrest element that has an adjustable angle of inclination is mounted on the corresponding end wall in a pivotal manner about a transverse axis. Laterally outward projecting bearing pins of the other inner lower end of the seat element or backrest element are guided in slots of a respective lifting device which is pivotally mounted on the lateral walls, by means of which the pivotally mounted element can be raised from a lowered seating position into a lying position.Type: GrantFiled: July 25, 2011Date of Patent: June 16, 2015Assignee: Curt Wuerstl Vermoegensverwaltungs—GmbH & Co.

Patent number: 8973991Abstract: A seat anchoring element for child safety seats or baby carriers has an anchoring element which can be secured to fixation elements on the vehicle seat, or to the vehicle body, by connectors at the ends of a separate strap system. The seat anchoring element comprises at least one front and rear securing element on the upper face for fixing the child safety seat or the baby carrier thereto, and least one tensioning device for those parts at the ends of which the connectors are located. The straps of the strap system can be wound onto a ratchet spool of the tensioning device and can be unwound after a locking mechanism of the ratchet is unlocked. A lever mounted pivotably with the seat anchoring element is coupled with the ratchet, wherein the bearing axis of the lever runs transversely to the longitudinal axis of the seat anchoring element.Type: GrantFiled: October 5, 2011Date of Patent: March 10, 2015Assignee: Curt Wuerstl Vermoegensverwaltungs-GmbH & Co.

Publication number: 20110089728Abstract: A child car seat has at least one seat part with side walls forming armrests and an impact cushion, which is insertable between the side walls of the seat part and/or placeable thereon and is supported at the side walls. The impact cushion ends in front of the child sitting in the child car seat and has a transversely extending recess for insertion of at least one transverse belt. There are fixing points provided at both sides, at the vehicle seat and/or the bodywork for fastening the car seat to the automobile via fasteners. There are also fastening points provided at the two side walls of the seat part and/or at the backrest part, for fastening the fasteners and the transverse belt to the seat part. The fastening points can be mounted to be rotatable, or the fasteners, lock elements, metal plates or other retaining means can be rotatably mounted at the fastening points, so that an optimal cable line of the tightened belt sections automatically arises.Type: ApplicationFiled: October 12, 2010Publication date: April 21, 2011Applicant: Curt Wuerstl Vermoegensverwaltungs-GmbH & Co.
