Abstract: A method is provided to check for presence of gas bubbles in an electronically slip-controllable motor vehicle brake system that includes brake circuits to which wheel brakes are connected, a pressure generator to charge the brake circuits with a brake pressure, and sensors to detect an actuating signal of the pressure generator and measure the brake pressures in the brake circuits. Disturbances are recognized by ascertaining from the signal a setpoint value for a brake pressure to be obtained and comparing it to an actual value of the brake pressure or by determining that an actual volume of the pressurizing medium displaced into the brake circuits, ascertainable from the signal, is greater than a limiting value that is determined for a setpoint value for the pressurizing-medium volume to be displaced into the brake circuits in order to generate the actual value of the brake pressure.

Abstract: A child carrier assembly for a bicycle is provided. The child carrier assembly of the invention includes a seat assembly for retaining the child, a frame assembly for supporting the seat assembly on the bicycle behind the bicycle seat, and an assembly for strapping the child in a seat assembly. The carrier assembly also includes a head supporting assembly for supporting the head of the child when the child is carried in the carrier. The assembly of the invention can be removed from the bicycle without the use of any tools.

Abstract: A bicycle handle grip assembly is provided. The handle grip assembly includes a flexible housing mounted along at least a portion of the outside surface of the handle grip. The housing communicates with the outside via a pathway that retains a reed assembly mounted therein. When the housing of the handle grip assembly is compressed, air inside the housing is forced through the pathway and past the reed assembly, thereby producing an alerting sound.

Abstract: A swivel grab bar assembly for a bicycle carrier is provided. The grab bar assembly is mounted on a bicycle child carrier forward of and above the child and includes a grab bar, an assembly for mounting the grab bar on the carrier, and a pivoting system which enables the grab bar to swivel or rotate from a first down position (in which a child may enter and exit the carrier) to a second upright position (so that the child is prevented from falling out the carrier).
