A seating arrangement for a vehicle having a cabin space is provided. The seating arrangement includes a vehicle, at least one front seat within the vehicle, and at least one rear seat arranged behind the at least one front seat of the vehicle. The at least one front seat is rigidly fixed to and suspended from a portion of the vehicle, thereby providing a free space underneath the at least one front seat, such that an occupant of the vehicle seated in the at least one rear seat is able to position at least a lower portion of one or both legs thereof in the free space underneath the at least one front seat. A flexible covering, such as bristles may be attached to the periphery of the vehicle floor opening, so that a driver's foot can pass from inside the vehicle cabin, to the ground outside the vehicle.

The invention relates to a vehicle comprising a first vehicle part (16) and a second vehicle part, wherein the first vehicle part (16) comprises a first running wheel (37, 38) rotatable about a first axis of rotation (59) and the second vehicle part comprises a second running wheel rotatable about a second axis of rotation. The first running wheel (37, 38) and the second running wheel have the same miming-wheel diameter. A first bearing means for rotatably mounting the first running wheel and a second bearing means for rotatably mounting the second miming wheel are interconnected by means of a joint mechanism (17) in such a way that the orientation of the first axis of rotation (59) and of the second axis of rotation relative to each other can be varied. By means of the joint mechanism (17), the vehicle can be transferred continuously from a first driving configuration with the first and second axes of rotation inclined relative to each other into a second driving configuration with the first and second axes of rotation parallel, and in the second driving configuration a distance of a first contact surface of the first miming (37, 38) from a second contact surface of the second miming wheel is less than one tenth of the running-wheel diameter.

The present invention comprises a weight distribution tag trailer, having at least some of the following features: (a) a frame assembly, including beams and cross beams and side axle beams, (b) an axle coupled to the frame assembly, (c) shims for optional position between an axle assembly and the side axle beams to allow adjustment of load and balance (d) at least two wheels rotatably mounted to the axle, wherein at least one beam includes an end complementarily sized to be received by a vehicle receiver hitch assembly, and at least one other beam includes a clamp for coupling the beam to a cross frame of the vehicle receiver hitch.

An active-passive differential series-parallel connection supporting leg, a gravity-based closing series-parallel connection supporting leg, and a six-degree-of-freedom position-adjusting robot platform are provided. The six-degree-of-freedom position-adjusting robot platform is formed of a plurality of legs distributed in parallel, and includes a frame, a distributed controller, and multi-chain parallel legs, wherein a plurality of legs are fixedly connected with the frame through a base. The present disclosure integrates an omnidirectional movement and position adjustment to solve problems that the existing position-adjusting platform is fixed or moved inflexibly, the structure is over complicated, the occupation space is excessive, and the movement error is large, and thereby effectively expanding application range of the six-degree-of-freedom position-adjusting robot platform.
