  • Patent number: 7712816
    Abstract: A movable floor device for a vehicle, which comprises a movable board disposed beneath feet of an occupant seated in an occupant seat, a drive source disposed below the occupant seat, and a driving-force transmission mechanism adapted, according to a driving force of the drive source, to input a force directed in a selected one of frontward and rearward directions of a vehicle body, into a rear portion of the movable board. The movable board is supported in such a manner as to be selectively displaced upwardly and downwardly in response to respective ones of the frontward and rearward forces input from the driving-force transmission mechanism. The movable floor apparatus of the present invention makes it possible to allow a lowermost height position of a movable board to be set at a lower level so as to cope with various seating postures with enhanced flexibility.

  • Patent number: 6318782
    Abstract: It is an object of the invention to provide an opening/closing rear component structure of a vehicle, comprising a luggage space being divided into a upper luggage space and a lower luggage space, a openable/closable door being provided to the upper luggage space and the lower luggage space respectively, and the door for the upper luggage space and the door for the lower luggage space being adapted to selectively adopt either a mode of opening/closing the door for the upper luggage space and the door for the lower luggage space integrally so that the upper luggage space and the lower luggage space may be opened/closed at the same time, or a mode of, opening/closing the door independently so that the upper luggage space and/or the lower luggage space may be opened/closed, whereby it becomes possible to selectively adopt an independent luggage space separated from the compartment (such a luggage space as a sedan-type vehicle has) or a large luggage space in which large luggage can be loaded and unloaded easily

  • Patent number: 5143167
    Abstract: In a four-wheel-drive motor vehicle of transversely-disposed engine type, an engine and a transmission are disposed so as to be longitudinally offset from each other and to locate a gravitational center thereof in a rearward position of an axle of front wheels, and in addition an output shaft of the transmission and a center differential are disposed coaxially. With this arrangement, imbalanced weight distribution of the vehicle body on front wheels can be corrected, and a longitudinally-compact layout of the power transmission device can be obtained. Further, a height of a bonnet can be lowered.

  • Patent number: 5129476
    Abstract: In the case where a steering shaft and an exhaust pipe are arranged in the longitudinal direction of vehicle body across a front axle in the four-wheel-drive motor vehicle of transversely-disposed engine type, such are arranged by utilizing a dead space between a front differential and a directional change gear. This arrangement can meet the required road clearance and other requirements, while preventing interference with differential, etc.

  • Patent number: 5078229
    Abstract: A four-wheel-drive motor vehicle with a transversely-disposed engine of such construction that a front differential which distributes motive power from a center differential to the right and left front wheels is arranged on the front axle and in the rear of the front differential, an engine and a transmission are arranged. By this arrangement, one-sidedness of the vehicle body weight to the front wheels can be relieved.

  • Patent number: 5064017
    Abstract: In the four-wheel-drive motor vehicle of transversely-disposed type, a front differential and a center differential are arranged coaxially on the axle line of front wheels, and an engine and a transmission are disposed transversely to the vehicle body in the rear of these differentials. This arrangement can relieve one-sided action of the vehicle body weight on the front wheels.

  • Patent number: 5040634
    Abstract: A motor vehicle with a transversely-disposed engine wherein a differential gear of a power plant is mounted transversely in the forward position of an engine, and a steering member is disposed in the upper position of an output shaft of the engine as well as in the rearward position of the engine. The advantages obtained in this arrangement are a reduced weight loaded on front wheels, a simplified steering system and a facilitated layout of the steering member. Knuckle arms are provided with long arm portions with which tie rods are connected. These tie rods are connected with the steering member at the center thereof. Accordingly, the tie rods can be long enough while necessary steering angle of the front wheels can be obtained. Thus, the toe angle fluctuation can be restrained and the steering rigidity can be improved.

  • Patent number: 5024482
    Abstract: A front body structure of a vehicle includes a side frame and a front wheel apron reinforcement, both extending in a lengthwise direction from front to rear of the vehicle. A suspension tower is secured between the side frame and front wheel apron reinforcement for supporting a suspension. A front wheel housing is also secured between the side frame and front wheel apron reinforcement for receiving therein a front wheel. Front and rear side wheel aprons extend in the lengthwise direction, constitute the front wheel housing, and are located on front and rear sides of the suspension tower, respectively. A junction member is provided between and secured to the suspension tower and each wheel apron to form a hollow frame section adjacent to the suspension tower. Bracket holders for holding brackets to support a front suspension arm and connect them to the front body structure are provided and are divided into two parts. Each part is integrally formed with one of the wheel aprons or one of the junction members.

  • Patent number: 4625931
    Abstract: A device for preventing meandering or free running of a web on a roll supported on a shaft on a machine, like a thermal printer. A stationary shaft is fixed to the frame. A core is rotatably mounted around the shaft. A reel mounted around the core has a carbon ribbon that is to be wound on it or unwound from it when the reel is rotated. A leaf spring between the core and the inner circumference of the reel frictionally connects the reel and the core so that the reel does not rotate idly of the core, but rotates together with the core. The core is held by a spacer at a predetermined distance along the shaft from the machine frame. A spring acting on the opposite side of the core pushes the core toward the spacer, whereby the core is frictionally restrained from freely rotating, which prevents web meander. Felt washers disposed between the core and the elements axially adjacent thereto smooth the rotation of the core and prevent wear thereof.

  • Patent number: 4542690
    Abstract: A heat-sensitive printing machine is disclosed. The printing machine includes a platen upon which a heat-sensitive printing medium may be placed. A printing head has raised portions defining the indicia to be printed. A heater is provided for heating the printing head. A reciprocator moves the printing head between a first position remote from the platen and a printing position wherein the raised portions contact a heat-sensitive printing medium located on the platen. The printing head is connected to the reciprocator by a pair of leaf springs whose cross-section is sufficiently small that no more than about 20% of the heat in the printing head is conducted to the reciprocator through the leaf springs.
