A wind direction adjusting apparatus which can appropriately adjust a wind direction with a simple structure is provided. A case body includes an upstream portion located in a relatively upstream side of the wind, and a downstream portion located in a downstream side of the wind with respect to the upstream portion and expanded in a short direction of an outlet from the upstream portion. Fins include end fins each having a fixed end positioned along an edge portion of the outlet in a longitudinal direction and an intermediate fin located between the end fins. The end fins and the intermediate fin pivot in a same direction in conjunction with each other. Each end fin is disposed so as to intersect an imaginary line in a wind passage direction along a narrowed portion in a state in which each end fin is pivoted to a downstream portion side.

A vehicle air register assembly includes a housing defining a cavity. An upstream portion of the cavity is disposed proximate to an inlet and a downstream portion of the cavity is disposed proximate to an outlet. Vertical vanes are disposed within the upstream portion. The vertical vanes direct air in a horizontal direction. A horizontal vane assembly is disposed within the downstream portion. The horizontal vane assembly directs the air in a vertical direction. The horizontal vane assembly includes at least one horizontal vane including a driver portion rotatably coupled to the housing proximate to the outlet and a follower portion coupled to the housing proximate to the upstream portion. The follower portion is rotatably coupled to the driver portion.

A gear system for pivoting blades of an air vent, which is releasable or disengageable. For this purpose, one embodiment provides a rack and pinion gear system comprising helical pinions, which engage with a toothed rack as a result of an axial force due to a helical spline when rotational driving, and thereby establish a drive connection with the blades.

A lever for an air vent assembly. The lever includes a first arm and a second arm, each extending from a base portion creating a guiding path therebetween. The first arm includes a first portion having a curved profile to facilitate abutment of the first portion with a movable disc of the assembly. The lever has a flexible third arm extending from the base portion and configured substantially parallel to the second arm. This shape and/or material of the third arm facilitates smooth and constant abutment of the first portion with the movable disc, and ensures a soft contact of the first lever against an inner surface of a housing of the assembly.

A low sound emission flow diffuser includes a diffuser housing, which limits or forms an installation space, through which a flow path for an air flow of air extends, starting at an inlet opening, which is limited or formed by the diffuser housing on its inflow side, to an outlet opening, which is limited or formed by the diffuser housing on its outflow side. The flow diffuser has a multi-piece, optionally three-piece, flow manipulator, which extends along the flow path between the inlet opening and the outlet opening, for absorbing airborne sound. The disclosure additionally relates to an air conditioning system of a motor vehicle including at least one such low sound emission flow diffuser.

A vane controller assembly for an air vent of a vehicle. Vane controller assembly includes a deco panel adapted to be fitted in the air vent, and a knob movably coupled to the deco panel using a shaft. The vane controller assembly includes an elastic member having a body portion that has a hole, and protrusion(s) configured on an outer surface of the body portion, which is adapted to engage and lock with a slot provided at a first end of the knob. The shaft passes through the hole of the body portion of the elastic member such that the elastic member is slidably and rotatably engaged with the shaft, and allows a user to adjust orientation of vanes of vane controller assembly in a required direction.

An air suspension apparatus for vehicle seats includes an air shutter connected to a supply port of a control valve configured to supply air so as to adjust the opening degree of an inner air channel through which air supplied to the control valve passes.

Two parallel blades are disposed at a distance behind one another, in a flow direction, in an air vent for a motor vehicle, which are jointly pivoted in a manner opposite one another by way of a coupling device, and disposing, between the two blades, a louver comprising blades, which are disposed next to one another and can be jointly pivoted parallel to one another, perpendicularly to the two other blades.

A slim air vent for a vehicle includes an inner wing disposed in a duct to horizontally rotate during manipulation of a knob, an outer wing and a support wing disposed in the duct to vertically rotate during the manipulation of the knob, a knob pin horizontally penetrating through the knob to rotate together with the knob during the vertical rotation of the knob and to guide the knob during the horizontal movement of the knob, and a link mechanism provided to connect one end of the knob pin and the outer wing to vertically rotate the outer wing and the support wing during rotation of the knob pin according to the vertical rotation of the knob.

An attachment structure of a generator and a working machine including a transmission case; and a PTO shaft protruding from the transmission case, includes a structure body attached to a side of the transmission case from which the PTO shaft protrudes, and includes the generator attached to the structure body.
