A front side member of an automobile has a rigid portion formed in a closed cross section by an inner panel and an outer panel and extending in the longitudinal direction of a car body, and a base portion extending inwards and downwards in the lateral direction of the car body from the rigid portion. The rigid portion is provided with a reinforcement arranged in the closed cross section and extending in the longitudinal direction of the car body. The reinforcement is shortened less than the inner panel at a top portion thereof and provided with a linear corner portion. As a result, an axis, which is one of rectangular coordinate axes as principal axes of the closed cross section and which maximizes a moment of inertia with respect to the axis, is formed so as to direct downwards from the outside to the inside in the lateral direction of the car body.

A structure of a panel includes a peripheral portion and an intermediate portion integrally provided with the peripheral portion. At least the intermediate portion includes a curved surface having a substantially constant sum of the maximum curvature and the minimum curvature at all the points on a surface of the intermediate portion. Further, the peripheral portion is formed as the same curved surface as the curved surface of the intermediate portion, or a curved surface having a curvature different from the curvature of the curved surface of the intermediate portion so as to enhance the panel stiffness of the peripheral portion.

A controller for a vehicle seat for optimally controlling the posture of a vehicle seat. An amount of a running condition of the vehicle is detected, and a controlled variable for a posture of the seat for appropriately holding an inertial force acting on an occupant seated in the seat is determined in correspondence with the amount of the running condition of the vehicle detected. In addition, an amount of displacement of a posture of the vehicle is detected, and the posture of the seat is controlled on the basis of the controlled variable for the posture of the seat and the amount of displacement of the posture of the vehicle. Since the posture of the seat is controlled in correspondence with not only the running condition of the vehicle but postural displacement of the vehicle, the holding characteristic of the driver's seat improves and permits driving with a comfortable and more stable posture.

System for accommodating sitting attitude of vehicle occupant

A spiral wound gasket having an annular body serving as a centering member which is integrally disposed at the inner periphery side of a gasket body formed by winding, in the form of a spiral. The gasket body comprises a metal hoop material and a filler material overlapping each other. When this gasket is disposed at fit-joint-type pipe connection portions of the exhaust pipe system in a motor vehicle, the annular body serves as a centering member to prevent the gasket body from protruding into the fit joint. This prevents the gasket body from deterioration and damage, thus assuring a high sealing property for a long period of time. Further, merely by inserting and fitting the gasket, the gasket may be automatically aligned and positioned with respect to the fit joint. Further, the inner peripheral surface of the gasket body and the annular body form an annular closed space, thus making the entire gasket into a lightweight design.

Spiral wound gasket

A vehicle windshield wiper structure has a wiper arm connected to a wiper head and supports a wiper blade which is adapted to be forced onto the surface of the windshield glass. A spring is provided to force the wiper blade into engagement with the windshield glass surface. The spring is engaged at one end with an intermediate portion of the wiper arm and at the other end with an end of a swingable lever which is pivotably mounted on the wiper head. The other end of the swingable lever is provided with a cam follower roller which is adapted to be engaged under a resilient force applied by the spring with a cam provided on a stationary part of the vehicle. The cam has a profile which is slanted at the opposite end portions so that the resilient force depressing the wiper blade into engagement with the windshield glass surface is decreased at each end of the stroke of movement of the wiper to thereby decrease the noise which may otherwise be produced when the wiper movement is inverted.

Wiper structure with variable wiping pressure

The present door for a motor vehicle includes a door glass, a door glass piece and a guide groove. The door glass piece has a substantially crank shape and a forward end sliding portion offset into the vehicle and secured to an end portion of the door glass, the sliding portion of the door glass piece being slidably guided by the guide groove on a door frame aligned to enable opening and closing of the door glass, while the outer surfaces of the door glass and the door frame are substantially flush with each other. According to the present invention the sliding portion of the door glass piece and the door glass are formed such that an angle formed by a center line of the sliding portion and the outer surface of the door glass is less than 180.degree., the outer surface of the vehicle being curved and the door glass conforming to the curvature of the outer surface of a vehicle body, which is continuously formed by the outer surfaces of the door glass and the door frame.

Construction of door in motor vehicle

A vehicle door comprising a door section having a door panel and a window frame, wherein the door panel includes an inner housing extending between an exterior and an interior of the vehicle. A door glass is slidably mounted between the window frame and the inner housing. The door glass has an arcuate configuration when viewed in cross section in the direction of the length of the vehicle and defines a projected normal arc of curvature corresponding to the arcuate configuration of the door glass when the door glass is in a closed position. The projected normal arc of curvature extends downward from a closed position of the door glass. A guide channel is provided for guiding the door between the closed position and an open position. The guide channel defines an actual arc of curvature when viewed in cross section in the direction of the length of the vehicle, which is displaced radially inwardly from the normal arc of curvature. Therefore, the door glass is slidably positioned to be closer to the interior of the vehicle when slid to an open position along the guide channel than if it were slid along the projected normal arc of curvature.
