In a buckle device, a buckle body is held in an upper part of a boot, and a lower part of the boot is supported from the lower side by a frame and a protector. Here, an upper left inclination surface of the boot and the lower left inclination surface of the protector are inclined in a downward direction as being directed inward in the right-left direction of the boot. Therefore, in a case in which a load is input to the boot from the upper side, it is possible to apply a displacement force to the boot inward in the right-left direction of the protector, and to suppress the downward displacement of the boot with respect to the frame and the protector.

Buckle device

In the buckle device, when or after torsional deformation of the torsion shaft has started and allowance of the drawing-out of the belt has started, the breaking portion of the shear plate is started to be deformed by the coupling hole side surface of the spool, whereby the breaking portion allows the rotation of the spool and allows the drawing-out of the belt. Therefore, the allowable drawing-out load of the belt can be made the sum of the load for torsionally deforming the torsion shaft and the load for deforming the breaking portion, and can be increased.

In this buckle device, a base end portion of a belt is folded back on itself to form a ring-shaped portion, and the belt is wound onto a spool in a state in which the ring-shaped portion of the belt has been inserted through an insertion hole in the spool. This enables a winding radius of the belt to be increased by the base end portion of the belt and enables a load at which the belt is permitted to be pulled out to be reduced, when the belt is pulled out from the spool.

In this buckle device, when a second wind of a belt is pulled out from a spool, a load at which the belt is permitted to be pulled out is small, whereas slide resistance of the belt with respect to a slide face is large. When a first wind of the belt is then pulled out from the spool, the belt pull-out permitting load is large, whereas the slide resistance of the belt with respect to the slide face is small. This enables variation in a load at which extending of a buckle body is permitted to be suppressed.

In a buckle device, when a belt starts to be allowed to be drawn, a fracture portion is deformed by a side surface of a connection hole of a spool, so that the fracture portion allows a rotation of the spool and allows drawing of the belt. Then, the fracture portion is fractured by the side surface of the connection hole. Therefore, a drawing allowance load of the belt when the belt starts to be allowed to be drawn can be increased.

Webbing guide includes: guide body through which webbing is inserted; front wall that contacts one side face of first opening edge part and second opening edge part; rear wall that contacts another side face of first opening edge part; and claw that contacts another side face of second opening edge part. Connection part connects guide body and rear wall and includes concave part, and leading end of first opening edge part enters into concave part when webbing guide is assembled with member for assembly.

An imaging device stores and photoelectric-converts incoming light from an object of which an image is to be captured with a CCD, and controls an output level of a picture signal obtained by signal processing an image signal output from the CCD. An output adjustment value of the picture signal in the output control is set to become 50 to 70 IRE according to a peak value of the picture signal when a test pattern is captured under standard conditions. Accordingly, it is possible to have a typical imaging device display a captured image darker, and thus enable imaging suitable for nighttime imaging and the like.

Imaging device and visual recognition support system employing imaging device

A second circuit separately extracts a synchronization signal and brightness signal from an image signal output from a camera for capturing an image of a subject. A gamma amplifier produces a gamma correction signal based on a brightness ratio characteristic in which a display brightness increases as the signal level of the brightness signal increases and the display brightness is set using a display brightness correction ratio which is preferably 70 to 90% of an equi-proportional display brightness correction ratio when the signal level of the brightness signal falls in a high-brightness range. A liquid crystal display receives the gamma correction signal and displays an image captured by the camera with the display brightness set in accordance with the brightness ratio characteristic while synchronizing with a drive timing signal output from a first circuit. Thus, the difference in display brightness between different high-brightness regions or subjects is made large, whereby halation which may otherwise occur between those regions or subjects can be prevented.

Night vision system and control method thereof

A vehicle visibility assist device is started up when a switching operation of a switch for an external vehicle light is detected and when it is determined by a brightness sensor that it is darker outside of the vehicle than a predetermined threshold. The visibility assist device projects infrared light to a region outside the vehicle, captures a reflection of the light, processes an image of the region outside the vehicle, and projects the image onto a surface visible to the vehicle operator.
