A recumbent apparatus for exercise and physical therapy providing a lower body workout, an upper body workout and cardiovascular conditioning, the apparatus comprising a frame having a forward end and a rearward end, the frame generally defining a longitudinal axis extending between the forward and rearward ends, a seat supported by the frame, a left leg assembly and a right leg assembly, the leg assemblies supported by the frame for pivoting movement about a pivot axis transverse to the longitudinal axis, the leg assemblies positioned generally toward the forward end and each including an upwardly extending leg lever terminating in a pedal, a left arm assembly and a right arm assembly, the arm assemblies supported by the frame for pivoting movement also about the pivot axis, the arm assemblies positioned generally toward the forward end and each including an upwardly extending arm lever terminating in a handle, the left leg assembly being connected to the right arm assembly enabling movement therewith and defining a first connected assembly, the right leg assembly being connected to the left arm assembly enabling movement therewith and defining a second connected assembly, the connected assemblies coupled by at least one generally stiff mechanical linkage to a cam such that forward movement in one of the connected assemblies induces rearward movement in the other the connected assemblies, thereby enabling contralateral movement of the arm and leg assemblies, a first belt coupled to the cam and a first one way clutch, wherein the cam is actuated by the stiff mechanical linkage in a first direction and the first belt is actuated by the cam, the first belt rotating the first one way clutch, a second belt coupled to the cam and a second one way clutch, wherein the cam is actuated by the stiff mechanical linkage in a second direction and the second belt is actuated by the cam, the second belt rotating the second one way clutch, the first and second one way clutches coupled with a pulley which is further coupled to a resistance device by a third belt, the resistance device providing resistance to the movement of the arm and leg assemblies about the pivoting axis.

An earth moving machine comprises a vehicle (2), a working device (10) mounted on the rear part (4) of the vehicle (2), a seat (14) rotatably attached to the vehicle (2) and able to rotate between a front position in which it is facing the front part (3) of the vehicle (2) and a rear position in which it is facing the rear part (4) of the vehicle (2), driving means (15) for the vehicle (2), and means (19) for moving the working device (10). The machine (1) also comprises a sensor (22) attached to the seat (14) to detect its position and enabling means operatively connected to the sensor (22) and to the movement means (19) for enabling operation of the movement means (19) at least when the seat (14) is in the front and rear positions, and for inhibiting operation of the movement means when the seat (14) is in at least one intermediate position between the front and rear positions, thus there being detected, during rotation of the seat (14), at least a front enabling zone (23) and a rear enabling zone (24) in which the movement means (19) are enabled, and at least one side inhibit zone (25) in which operation of the movement means (19) is inhibited.

An infant car seat 16 is mounted on a stationary platform 28 which comprises a lower horizontal plate 42 and a vertical plate 26 extending from one edge thereof. The stationary platform 28 is secured by the seatbelts 68 against the rear seat 14 of the automobile 12 adjacent the door 18. The child seat 16 is pivotably attached to a vertical portion 26 of the stationary platform 28 by means of a hinge assembly 24 that allows the user 20 to stand outside of the vehicle 12 and swing the seat 16 into a position to enable them to place the child 22 directly therein in a face-to-face manner and then swing the seat back into place and lock it into a secure position. The child seat is secured to a seat support mechanism comprising a support bar 44 pivotably connected to a hinge assembly 24 that slides along a track assembly 30 so as to maintain the car seat in a protected area within the vehicle when in the pivoted position.

A lift-up mechanism (50, 150) installed inside a vehicle serves to move a seat unit (10, 110) into or out of the vehicle. The seat unit (10, 110) is used as a passenger seat inside the vehicle and as a wheelchair outside the vehicle. Connecting plates (56, 156) are disposed on the lift-up mechanism (50, 150) permit the lift-up mechanism (50, 150) to be connected to the seat unit (10, 110) by inserting the connecting plates into connecting recesses (40, 140) formed in the seat unit (10, 110). Front wheels (60, 160) and rear wheels (70, 170) of the seat unit (10, 110) can be retracted and extended. A drive unit having an electric motor or similar drive may be provided to retract and extend the front wheels (60, 160) and the rear wheels (70, 170). An attitude changing arrangement may be provided to automatically change the attitude of the front wheels (60, 160) when the front wheels (60, 160) and the rear wheels (70, 170) are retracted.

A longitudinal support base 30 is provided with a rotating support base 10 that can be slide in a longitudinal direction of the vehicle. A seat body is placed on the rotating support base 10 via a rotary disc 13 so as to rotate. The longitudinal support base 30 is provided with an intermediate gear 22 that is engaged with a rack 21 extending in the longitudinal direction of the vehicle seat. The seat body 2 side is provided with a pinion gear 24 that is engaged with the intermediate gear 11. The rotary disc 13 is rotated by means of a driving force of an electric motor 41. Thus, when the electric motor 41 is rotated, the seat body 2 rotates and slides in the longitudinal direction.
