Abstract: A lens assembly includes a lens housing, a flexible washer, and a lens module. The flexible washer and the lens module are disposed within a tubular sidewall of the lens housing. The washer is disposed axially between a mating surface of the lens module and a base surface of the lens housing. The lens housing and lens module include corresponding threads, and rotation of the lens module along the threads of the lens housing adjusts the axial position and focus of the lens module. The washer is the only component axially between the lens module and the lens housing and directly contacts the base surface and the mating surface. When compressed, the washer exerts an axial force on the lens module and lens housing, such that the friction on the threads is increased and the lens module is held in place.

Abstract: Vehicle camera assemblies comprising integrated self-cleaning assemblies. In some embodiments, the self-cleaning assembly may be configured to engage the camera housing and/or assembly by way of a snap-fit connection. In some embodiments, the snap-fit means may comprise a flexible coupling member. In some such embodiments, the snap-fit means may further comprise a rigid coupling member. The cleaning assembly may be removably coupleable with the camera housing to allow for cleaning, maintenance, and the like.

Abstract: A camera arrangement for a motor vehicle is provided. The camera arrangement includes a front housing for at least partially enclosing a camera system. The front housing has a housing opening formed therethrough for allowing light to pass through to the camera system. A window is at least partially transparent to the light and covers the housing opening. A retainer is disposed adjacent to the window and includes a snapfit arrangement that engages the front housing to help hold the window in place relative to the front housing.

Abstract: A camera module assembly includes a camera core disposed with an outer housing. The outer housing includes a front shell with a window and a rear shell. The camera core includes a lens assembly, and sensor assembly, and a sensor housing. The sensor assembly is disposed within the sensor housing, and the sensor housing is fixed to the lens assembly. The sensor housing includes a plurality of grommets disposed within an interior cavity, and the sensor assembly is pressed against the grommets to hold the sensor assembly in place within the sensor housing and relative to the lens assembly when the sensor housing is fixed to the lens assembly. The camera core is inserted into the front shell against rubber bumpers, and the rear shell is fixed to the front shell to close the outer housing.

Abstract: A camera shutter arrangement is provided. The camera shutter arrangement includes a motor. A pinion gear is operatively coupled to the motor. An integral paddle-gear member includes a paddle portion and a gear portion. The gear portion extends from the paddle portion and meshes with the pinion gear to move the paddle portion between a first position and a second position when the motor is energized.

Abstract: A system for retaining a sensor assembly includes a mounting plate having a mounting area for the sensor assembly, a sensor assembly having a sensor assembly plate with a perimeter, and a retainer ring having at least one spring member. The at least one spring member of the retainer ring is configured to bias the sensor assembly substantially toward at least one datum, such that a portion of the perimeter of the sensor assembly plate is directly adjacent to the at least one datum.

Abstract: A camera system exhibiting reduced effects from temperature changes. The camera system includes an IR sensor; an optical arrangement adapted to focus incoming light onto the sensor; a processing arrangement adapted to process signals produced by the sensor; a heatsink in thermal contact with and is adapted to transfer heat energy away from, the processing arrangement; and a thermal equalizer. The thermal equalizer at least partially surrounds and is in thermal contact with the optics/sensor unit and is formed at least partially from a material having a high thermal conductivity. The thermal equalizer conducts heat energy from warmer to cooler parts of the optics/sensor unit. The thermal equalizer is also thermally insulated from ambient air surrounding the camera system and from the heatsink.

Abstract: An apparatus (10) for helping to protect an occupant of a vehicle includes an inflatable vehicle occupant protection device (12). An inflator (14) provides inflation fluid for inflating the protection device (12). A vent member (30) includes at least one vent opening (62) for venting the inflation fluid. A vent cover (100) has a closed condition for blocking fluid flow through the at least one vent opening (62) and an open condition for permitting fluid flow through the at least one vent opening. The vent cover (100) includes a side wall (110) that has at least one portion (134, 372) that projects from the side wall into the vent member (30) to help maintain the vent cover in the closed condition.
