twoop
Twoop reinvents the classic bicycle child seat. Twoop can also be used efficiently when no child is sitting in it. In addition, it offers storage space for small luggage even when the child is seated, which is not the case with commercially available models.
A plastic shell forms the basic element, to which a frame- work of aluminium tubes and plastic joints is attached. A textile is stretched over this framework. To convert the seat into the transport box, a latch in the centre of the seat is actuated and simultaneously pulled upwards and forwards. This movement causes the partly elastic textile to stretch open. This creates space for e.g. a shopping bag. The legs and seat are firmly connected to each other. As a result, the legs are automatically folded back and up when in the boxed state, making them less exposed and eliminating unnecessary air resistance. The foot sections are easily adjustable and can thus be indi- vidually adapted to the size of the child.
Twoop was developed as part of a collaborative module between ETH Zurich and ZHdK. In a team consisting of three industrial design students and one mechanical engineering student.
