An illumination device includes a light source part for emitting light with an intensity distribution approximately uniform in a first direction and a fly-eye lens into which the light is entered. The light source part and the fly-eye lens are arranged such that the first direction is inclined with respect to vertical and horizontal directions of arrangement of lens cells in the fly-eye lens. Since illumination light is entered into the fly-eye lens in a state of inclining with respect to the fly-eye lens, the number of superimposition patterns on the fly-eye lens is increased and illuminance non-uniformity in illumination light is suppressed.

A guide convex portion is formed on a base plate in parallel to an illumination optical axis. Further, a fixed-side supporting member is provided in the base plate. A first opening is formed in an upright portion of the fixed-side supporting member. A slide supporting member can be provided on the base plate. A second opening is formed in the upright portion of the slide supporting member. By inserting a tapered rod into the second opening at its light incidence side and by moving the slide supporting member along the aforementioned guide convex portion, the slide supporting member is stopped at a predetermined position and, at this position, the slide supporting member is fixed.

A projection-type image display device includes three light sources respectively configured to emit a different colored outgoing light, a light combining unit configured to combine outgoing lights, and a projection unit configured to project a combined light combined by the light combining it. The projection-type image display device includes a first cooler configured to cool a first light source of the three light sources, and a second cooler configured to cool a second and a third light source of the three light sources except the first light source.

An ion wind generator (20) is arranged on one side of a light source (1). The ion wind generator (20) produces an air current by negatively ionizing air by corona discharges at a needle electrode (21), or negative side, and drawing the negatively-ionized air at a cylindrical electrode (22), or positive side. The air current blows toward the light source (1) and removes heat generated by the light source (1). An ultraviolet ray from the light source (1) is introduced to a vent of the ion wind generator (20) by a first dichroic mirror (4) and a ultraviolet ray reflection mirror (17). Though air exhausted from the vent includes ozone (o3) produced by corona discharges, the ozone is decomposed by the ultraviolet ray.

An air bag system comprises a housing, an inflator, an air bag, a cover, and connecting and fixing members. The inflator is supported on the housing and upon occurrence of a collision accident, blows out high-pressure gas. The air bag is supported in a folded form on the housing and in the event of the collision accident, is inflated by the high-pressure gas. The cover extends over the folded air and has convex portions formed on an inner wall thereof by inwardly thickening portions of the cover. The housing has engaged portions formed on an outer wall thereof and adapted to cooperate with the convex portions, each of the engaged portions being maintained in engagement with a respective one of the convex portions when the cover is connected to the housing. The connecting and fixing members extend through the respective convex portions and the engaged portions with the engaged portions maintained in engagement with the corresponding convex portions.

A guide tube for a passive seat belt system is disclosed. The guide tube is adapted to be arranged along a vehicle body to guide a slider drive member. The guide tube is constructed of a first guide tube member for allowing the slider drive member to extent therethrough and a second guide tube member having higher flexural rigidity than at least the first guide tube member and adapted to be mounted on the vehicle body by means of at least one tube bracket. The first guide tube member is fitted within the second guide tube member.

A seat belt is composed of a webbing adapted for restraint of the upper torso of an occupant, connected retractably at the inboard end thereof to a retractor provided on the central side of the room of a vehicle and fastened at the outboard end thereof to a latch member releasably engageable with a first member mounted on the sash of an associated door; and a second member provided within the room of the vehicle at an outer and lower location thereof, to which the latch member with the outboard end of the webbing fastened thereto is releasably engageable. The first member may be provided displaceably along a guide rail provided on the body of the vehicle adjacent the associated door.

An automatic seat belt system includes a guide rail arranged along a predetermined path within the room of an automobile, a runner provided movably on the guide rail, and a drive member for causing the runner to move in such a way that a webbing fastened to the runner is displaceable between an occupant restraining position and an occupant non-restraining position. The system further comprises a plurality of brackets for mounting the guide rail on the body of the automobile and means for positioning the brackets at desired locations relative to the length of the guide rail. The automatic seat belt system of this invention allows to reduce the material and machining costs upon fabrication of its guide rail and permits easy positional registration or matching between the guide rail and its brackets upon mounting the guide rail on the body of the automobile.
