A vehicle door security system comprising at least one deadbolt and respective operational elements, wherein the deadbolt secures at least one of a pivoting door and a roll up cargo door. The deadbolt toggles between an engaging configuration and a released configuration. The deadbolt can include an inertial release mechanism that disengages the deadbolt from the engaging configuration when the vehicle is subjected to a sudden impact. Alternatively, the deadbolt can be opened using a manual release mechanism located externally from the vehicle.

A lock suitable for use in a motor vehicle door has a rotary latch, a locking wedge, a pawl, a setting device, and a transmission device wherein the rotary latch cooperates with the locking wedge to be locked in a locking position by the pawl. Upon actuation of a manipulator, the setting device brings the pawl electrically at least into one opening position. The transmission device brings the pawl into its opening position by actuation of the manipulator over a displacement range which is greater than a displacement range of an electric unlocking.

An automobile vehicle lock is released under normal operating conditions by an electric motor. Under degraded conditions, a mechanical release of the lock is enabled. This allows the motor providing electrical release of the lock to be simply dimensioned for release under normal operating conditions with no requirement to over-dimension the motor to ensure the lock will open under degraded operating conditions. Because release of the lock is mechanical under degraded operating conditions, enablement of the mechanical release is provided by a low-power standby motor. This allows a compact and inexpensive standby power source to be employed.

A door handle assembly for opening a door of a vehicle includes a handle portion and a lever or actuating member for actuating or releasing a latch mechanism of a vehicle door. The door handle assembly includes fewer components than known door handles and is reversible or suitable for use at either side of the vehicle. The door handle assembly may include a counterweight and lever mechanism at the base of the door handle assembly, such that the components do not extend substantially into the door cavity. The counterweight may be positioned rearwardly and outwardly of a pivot axis of the lever mechanism when the handle is at an initial or non-opening position, thereby providing enhanced retention of the door handle assembly during vehicle collisions.

A blocking apparatus is cooperable with the latch lever of a vehicle door latching mechanism to prevent the latch lever from moving during a crash event, which prevents the latching mechanism from allowing the vehicle door to open. The blocking apparatus includes a housing supporting a linearly movable plunger engagable with a cam surface on the latch lever and a blocking member pivotally mounted for movement between a normal position and a blocking position. The blocking member moves into the blocking position due to the imposition of crash forces on the blocking member during a crash event. A centering spring mechanism biases the blocking member into the normal position and can return the blocking member into the normal position to permit movement of the latch lever after the crash event has occurred. The plunger is biased into engagement with the latch lever so as to move with the cam surface.

A vehicle door includes a powered latch mechanism and an interior door handle having first and second sensors disposed on opposite sides of the interior door handle. The first and second sensors are configured to detect the presence of a user's hand to control operation of the powered latch mechanism. The powered latch may be unlatched if an unlatch switch is actuated and the first and second sensors detect the presence of a user's hand.

A hood lift mechanism for reversibly increasing the energy absorption capability at appropriate force levels of a vehicle hood includes a vehicle hood; an active material in operative communication with the vehicle hood, wherein the active material comprises a shape memory alloy, a ferromagnetic shape memory alloy, a shape memory polymer, a magnetorheological fluid, an electroactive polymer, a magnetorheological elastomer, an electrorheological fluid, a piezoelectric material, an ionic polymer metal composite, or combinations comprising at least one of the foregoing active materials; and an activation device in operative communication with the active material, wherein the activation device is operable to selectively apply an activation signal to the active material and effect a reversible change in a property of the active material, wherein the reversible change results in an increased clearance distance between the vehicle hood and an underlying component.

An outside handle assembly for an automobile is constructed to have a handle body 3 connected to a handle base 2 secured to an automobile panel 1, and a connecting lever 7 swingably connected to the handle body 3 and driven vertically by an operating force applied to the handle body 3 so that an engaging portion 4 formed toward its lower end may push an unlocking lever 6 in a locking device 5 to release the locking device 5 from its locking state. The engaging portion 4 is formed to be disengageable from the unlocking lever 6 upon swinging of the connecting lever 7 toward the center of the automobile body. The handle base 2 is provided with a panel deformation detector 8 protruding toward the connecting lever 7. The connecting lever 7 being urged toward the panel 1 by urging member 9.

A hood latch release mechanism for a motor vehicle of the type incorporating a hood which pivots at near the front edge of the hood. The hood latch release system enables the hood to be opened in a manner to provide enhanced pedestrian impact protection in the event of an impending pedestrian impact with the hood. The system incorporates a hood latch mechanism which is manually actuatable by the operator to permit access to the vehicle's engine compartment and operates automatically to the response to an impending pedestrian impact. The hood latch release system may be implemented with an active hood lifting actuator.

An integrated inertia locking mechanism may be incorporated with a door handle assembly and is particularly beneficial in acceleration events, such as a multiple axis crash, by counteracting the forces of inertia caused by such crash. In an exemplary aspect, the integrated inertia locking mechanism will prevent the door latch mechanism, which releases the door, from releasing and the door opening during a multiple axis crash. After the crash, or when the crash force is removed, the integrated inertia locking mechanism will allow the latch mechanism to function normally, thereby permitting the door to be opened and the occupants to exit from the vehicle.
