  • Patent number: 12145685
    Abstract: Disclosed is a bike trailer having a main frame and a seat structure. The main frame defines an accommodating space for a passenger or load to be transported. The seat structure is transferable between an operational state in which the seat structure forms a seating area for the passenger, and a stowed state in which the seat structure is folded away thereby allowing the transport of loads other than passengers. The seat structure comprises a backrest portion with a seating side for at least partially contacting the back of a passenger. The backrest portion is accommodatable in the bike trailer such that at least the seating side of the backrest portion is protected against contact with loads to be carried when the seat structure is in the stowed state.
