The present invention provides a mechanism for operating a vehicle split seat whereby operation levers of two seat backs can be arranged compactly on a wall surface of a luggage compartment or the like such that the two operation levers have the same pivot support point, without impairing operability of the levers. Two operation leversare respectively connected to locking mechanisms of at least two adjacent seat backsB by way of operation cables, the operation leversbeing formed of a central leverand an outer leverprovided outside the central lever having the same pivot support point, operation parts being provided on the free end sides of arm parts of both the leversand operating spaces X, Y, Z which allow both the leversto be operated individually also being provided.

The invention is intended to improve operability of a seat unit in a process of turning it from an approximately horizontal storage position to a seating position. An upper end of a seatback (SB) in its seating position and a rear end of a seat cushion (SC) are joined together by a string (), and two helical springs (biasing members) are provided at a forward portion of the seat cushion (SC). The first helical spring () exerts an upward biasing force which is smaller than the weight of the seat cushion (SC) against the seat cushion (SC), while the second helical spring () exerts an upward biasing force which is larger than the weight of the seat cushion (SC) against the seat cushion (SC). With this arrangement, a rear portion of the seat cushion (SC) is lifted when the seat is turned from the seating position to the storage position, and a small force is needed for lifting the seat cushion (SC) when it is turned in a reverse direction. The seat unit can be brought to the seating position by a single action since the seatback (SB) and the seat cushion (SC) are joined to each other by the string ().

An engine room structure of an automotive vehicle is provided with a power transmission unit consisting of, for example, a transfer, between a pair of left-hand and right-hand front side frames, a front axle extending outside from the power transmission unit in the transverse direction of the vehicle body. The steering rack functioning as an element of the front-wheel steering mechanism is so disposed within the engine room as to extend in the transverse direction of the vehicle body and as to lie in the position underneath the spower transmission unit. In other words, the power transmission unit is disposed in the position above the steering rack. This arrangement for the power transmission unit and the steering rack can provide a space between them, thereby lowering the positions of the front side frames.

A dual type exhaust system is used in an automobile having an internal combustion engine with transversely mounted front and rear rows of cylinders. Two exhaust pipe assemblies extend from the front and rear rows of cylinders, respectively, toward the back of the car body. The two assemblies are arranged side by side in a space formed in a floor panel. The exhaust pipe assemblies are, respectively, provided with catalytic converters offset in a lengthwise direction of the car body with respect to the space relative to each other so as to be arranged in a straight line in the space.

An air bag system for an automobile comprises a collision detector for detecting a collision of the automobile, an inflater for generating gas under pressure, based on an output from the collision detector, and air bag device, mounted on a front body member located in front of a seat, for receiving the gas from the gas generator, the gas causing the air bag device to take a predetermined inflated configuration. A seating condition sensor detects a seating condition of a passenger seated on the seat, taking into consideration seat position, reclining angle, passenger size, and posture. A control unit controls operation of the air bag device, in accordance with the seating condition of the passenger, so that the air bag inflated is brought into an optimal contact with the passenger.
