PURPOSE: A cruise cable interlocking device and the method are provided to improve traveling stability of a vehicle by removing the time delay and overshoot generated in constant-speed traveling by interlocking the cruise cable with an accelerator cable and to remove bang noise generated in taking off the cruise cable by a cruise actuator in releasing the constant-speed traveling. CONSTITUTION: A cruise cable interlocking device is composed of a movement measuring unit for measuring the movement of an accelerator cable(53); an auto-cruise unit(63) for calculating the movement of a cruise cable(67) according to the measured movement of the accelerator cable and outputting an electric signal for moving the cruise cable; and a cruise actuator(65) driven according to an output signal of the auto-cruise unit to move the cruise cable. The movement measuring unit comprises sensing objects(71) mounted at the accelerator cable and the cruise cable, respectively and an infrared sensor(73) for measuring the movement of the accelerator cable by measuring the movable distance of the accelerator cable by the monitoring of each sensing object.

PURPOSE: A device for measuring pressure of vehicle of a wind tunnel test is provided to supply sufficient data for the cooling of an engine and a brake and the damages of a vehicle body by measuring pressure for wind velocity in the middle as well as in the front and rear of the vehicle in a wind tunnel test. CONSTITUTION: A device for measuring pressure of vehicle of a wind tunnel test is composed of a traverse system(1), a rotary arm assembly and a control unit(30). The traverse system is mounted at the upper part to make a measuring unit(A) of a wind tunnel device move forward and backward the vehicle along a test space, wherein the wind tunnel device measures pressure generated in the vehicle by passing wind through a wind tunnel mutually connected by the vehicle that is positioned at the test space. The rotary arm assembly is mounted to the traverse system by a medium of a traverse adapter(1') to freely rotate and move along the vehicle and measure pressure for a voluntary spot of the vehicle. The control unit operates and controls the rotary arm assembly, and processes and analyzes data for measured pressure of wind velocity.

PURPOSE: A headrest apparatus of a seat for a vehicle is provided to fix a position of a head to be comfortable regardless of the position of the head of a passenger by applying a three-part structure to the headrest. CONSTITUTION: A headrest apparatus of a seat for a vehicle comprises a pad portion(40), a stay portion(2) and a cover. The pad portion of a three-part structure comprises right and left side pads(42) rotating on a Z axis and a center pad(41) rotating on a Y axis. The stay portion is a three-part structure as a stay body, a rotating stay of the center pad and a rotating stay of the side pad. The stay body includes a cross member having a hemispheric gear on both ends thereof and a pair of vertical members having a mounting end on an upper end thereof, wherein the cross member and the vertical member are integrally formed. The rotating stay of the center pad having a pair of gears is combined to the mounting end. The rotating stay of the side pad has a hemispheric tooth groove to be engaged with the hemispheric gear. The cover covers the pad portion including the stay portion.

PURPOSE: A clip structure for mounting a rear bumper is provided to improve assembly efficiency and firmness by mounting the rear bumper at a vehicle body only with a holder unit and a fixed unit. CONSTITUTION: A clip structure for mounting a rear bumper is composed of a fixing unit(11), and a holder unit(12). The fixed unit includes an elastic fitting piece(13) having protrusions(13a,13b) coupled to a coupling hole formed at a vehicle panel, and a fitting member(14). The holder unit is fixed to the fitting member, and includes an end unit(15a) coupled to a mounting bracket, and protrusions(15b,15c) formed at the upper and lower part of the end unit.
Abstract:
PURPOSE: A vehicle aerodynamic wind tunnel testing system is provided to obtain aerodynamic characteristics of vehicle body through an accurate test by removing the air pressure difference between the wind tunnel testing unit and balance chamber. CONSTITUTION: A vehicle aerodynamic wind tunnel testing system comprises a balance chamber(21) arranged underneath a turn table(15) at a bottom surface(7) of a wind tunnel testing unit(1), in such a manner that the balance chamber is sealed from outside and includes a balance system(19); and a pressure control unit arranged to the balance chamber, and which detects the air pressure difference between a wheel pad(13) and an interior of the balance chamber and removes the air pressure difference by adjusting the air pressure in the balance chamber. The pressure control unit includes a pressure difference sensor(23) connected to the wind tunnel testing unit, and which detects the air pressure difference between the balance chamber and the wind tunnel testing unit and outputs a signal; an air supply blower(25) arranged at a side of the balance chamber, and which supplies external air into the balance chamber; an exhaust blower(27) arranged at the other side of the balance chamber, and which exhausts air from the balance chamber to outside; and a pressure controller(29) for controlling air pressure in the balance chamber by controlling the rotational frequency of the air supply blower and the exhaust blower in accordance with the signal output from the pressure difference sensor.

Abstract:
PURPOSE: A rear bumper for a vehicle is provided to increase the productivity and manufacturing cost of the bumper and to improve shock absorbing performance by constructing the rear bumper with two parts producing it from two kinds of raw materials, and forming a back beam main body in the form of E-shaped section. CONSTITUTION: A rear bumper for a vehicle comprises a bumper cover(1) and a back beam(2). The bumper cover(1) is manufactured from engineering synthetic resin. The back beam(2) is manufactured from injection-molding synthetic resins such as polycarbonate and the like. The back beam(2) is disposed in the inner center of the bumper cover(1). The back beam(2) has a back beam main body(20). The back beam main body(20) is E-shaped in cross section. A closed surface of the back beam main body(20) comes in contact with the inside of the bumper cover(1). A plate-like rib(21) is integrally formed with the back beam main body(20) in the upper end thereof. A bumper stay(22) is integrally formed with the back beam main body(20) in the opposite ends thereof. A zigzagged rib(23) is integrally formed with the back beam main body(20) within a cavity thereof.
