The invention relates to a bicycle trailer, in particular for transporting children, comprising a chassis (1, 23) and a frame which is connected to the chassis for a passenger compartment. The trailer has at least two wheels (2, 21) and can be provided with a towbar (3, 22) for hitching to a bicycle and at least one third wheel in order to use the bicycle trailer as a stroller or as a jogger. The trailer has a lighting device (14, 35) and a push handle (6, 25). The aim of the invention is to provide such a bicycle trailer in which the handling of the lighting device is simplified. According to the invention, this is achieved in that at least one lighting device is integrated into the push handle or into a coupling for securing the push handle to the frame.

In an aspect a vehicle is provided, and includes a frame a front wheel and a rear assembly. The front wheel is rotatably mounted to the frame. The rear assembly includes a first rear wheel support and a second rear wheel support. Each of the wheel supports is movably mounted to the frame. The rear assembly further includes a first rear wheel and a second rear wheel. The first and second rear wheels are rotatably mounted to the first rear wheel supports respectively. The rear assembly is positionable in a first position in which the first and second rear wheels are substantially immediately adjacent one another to operate as a single rear wheel, and a second position in which the first and second rear wheels are spaced apart from one another.

A modular transporter comprises a universal chassis that can be linked with a variety of user modules. The universal chassis comprises a base that includes a quick connector and complex geometric surfaces on its sidewalls that function to secure a user module thereto. The quick connector allows for quick assembly/disassembly of a user module to and from the base of universal chassis. A plurality of suspension arms may be removeably connectable to the base such that modular transporter may be configured in a number of transport configurations. An ergonomic handle assembly may be coupled with the base for pushing, pulling, towing, etc. When disassembled, the modular transporter can be folded into a storage and/or quick fold mode and stored in a modular storage system. The modular storage system can be mounted to a trailer hitch by a linking mechanism for further transport.

Disclosed is a seat for a pushchair and/or for a doll's pram, in which a coupling unit is arranged between the back rest and the leg rest, the coupling unit carrying out an opposite movement transformation of the leg rest synchronous or offset in time when lowering the backrest, and the leg rest is moved back into the lower pivot position when the back rest is raised or is released for putting back in place.

A convertible car seat to stroller device includes a car seat that has a frame, which is rigid. A handle, which is extendable, is coupled to the frame. One of pair of cross supports, each comprising a front member and back member, is pivotally coupled to a bottom of the frame proximate to a left side of the frame. The other of the pair of cross supports is pivotally coupled to the bottom proximate to a right side of the frame. A front axle is rotationally couple to the front members. The front axle is coupled to a pair of front wheels. A back axle is rotationally coupled to the back members. The back axle is coupled to a pair of back wheels. The car seat is couplable to a base, which is couplable to the interior of a vehicle.

A convertible car seat, carrier and stroller device includes a car seat that has a frame, which is rigid. The car seat is shaped and sized to a child. A handle, which is extendable, is coupled to a back of the frame. A wheel assembly is coupled to and positioned in a housing that is coupled to a bottom of the frame. The wheel assembly is extensible from the housing and operationally coupled to the handle. Extending the handle lowers the wheel assembly and retracting the handle raises the wheel assembly. The car seat is couplable to a base that is configured to couple to an interior of a vehicle. The base is couplable to the interior of a vehicle and positioned to secure the car seat in the vehicle.
