Patent number: 5134733Abstract: A car bed for an infant comprises a cot body having a generally rigid rim providing support for rigid end portions, side portions and a bottom portion. A U-shaped handle has the ends of its limbs pivotally attached to the end portions of the cot body for angular movement about an axis extending longitudinally above the center of gravity of the cot body, between a position in which said limbs are perpendicular to said bottom portion and a position in which the handle is located to one side of said opening. In use, a seat belt is received in guide formations on the handle. Since the handle is located above the center of gravity of the car bed as a whole, the cot body will rotate as a unit deceleration, so that the bottom portion of the cost body is displaced forwardly in an arcuate path to a forwardly and upwardly inclined position.Type: GrantFiled: September 23, 1991Date of Patent: August 4, 1992Assignee: Britax Romer Kindersicherheit GmbHInventors: Hermann Wetter, Waldemar Czernakowski

Patent number: 4159127Abstract: Safety apparatus for restraining a seated occupant in a vehicle may comprise a tunnel-shaped body to restrain the lower torso of a large child or an adult, the body providing a base on which a movable chest-restraining panel is pivotally mounted. In the case of a small child, the lower torso restraining means includes an additional seat providing a base, for example, with a separate fixed panel and/or side portions, on which the chest restraining panel is pivotally mounted. The straps at each side of the occupant's body anchor the lower torso restraining means to the vehicle while enabling limited inertial movement relative to the vehicle seat. If the vehicle decelerates suddenly, the occupant's inertia moves the lower torso restraining means away from the seat until the straps are tensioned and act on lever means to pivot the chest restraining panel into its operative position. Either the lever means, or other locking means, may act as a stop to prevent return movement of the chest restraining panel.Type: GrantFiled: March 27, 1978Date of Patent: June 26, 1979Assignee: Romer-Wingard Autogurte GmbHInventors: Waldemar Czernakowski, Hermann Wetter, Ludwig Berger

Patent number: 4090735Abstract: A safety harness to restrain the operator of an earthmoving vehicle. The harness includes a pelvis belt connected to respective shoulder belts, each end of the pelvis belt and the shoulder belts are connected to belt retractors lockable by means responsive to both belt speed and the inclination of a vehicle. The vehicle inclination response of each retractor is similar, so that they act simultaneously, and a device is provided for adjusting the vehicle inclination response independently of the belt speed response to give the operator freedom of movement with safety restraint. The device may be coupled by cables to respective levers for locking the retractors, disabling the vehicle inclination response or for making the vehicle inclination response effective or by a double-acting solenoid having an armature for achieving the same effect.Type: GrantFiled: November 21, 1975Date of Patent: May 23, 1978Assignee: Romer-Wingard Autogurte GmbHInventor: Waldemar Czernakowski
