Abstract: An active bumper assembly for mounting to a vehicle is disclosed. The active bumper assembly includes a bumper that may be hingedly connected to a vehicle. When the bumper is in the inactivated position it is disposed behind the outer edge of the vehicle. When activated, the bumper is moved to an activated position, which is lower with respect to the inactivated position and extends below the outer edge of the vehicle. A sensing system detects an impending collision and generates a signal to which an actuator responds, moving the bumper from the inactivated position to the activated position. A locking member, configured to be interconnected between the bumper and the vehicle frame, then secures the bumper in the activated position.

Abstract: There is provided a tactile sensor that is a status sensor that move between inactive and active states. The tactile sensor can cover a large area and can be in the form of long strips. Its construction allows it to cover surfaces that are flat or curved or that include bends. In an exemplary application, these tactile sensors may be used as vehicle bumpers or in other applications where contact with an object, surface or the like needs to be detected. Activation of the sensor, typically coupled to a control system that controls motion of the vehicle, may cause the vehicle to shut off, typically ceasing motion, within a predetermined distance.
Abstract: A road vehicle is disclosed having a bumper assembly fitted to the rear end of the vehicle. The bumper assembly includes a beam extending across the rear end of the vehicle and supported by an arm from the vehicle so that the beam is displaceable from a rest position in a direction towards or beneath the vehicle in the event of contact with an obstacle.

Abstract: An automatic safety protector relates to a safety protecting device for a traveling motor vehicle. It is installed with a set of automatic flameout, braking mechanisms in front of the head of a motor vehicle, and a shock absorbing device is mounted between a fender-guard and a frame side member. When motor vehicle is in collision, the former realize automatic flameout and braking, and the latter buffers the impact force on collision, thereby the loss due to a collision accident is minimized.
Abstract: In accordance with the teachings of the present invention, a robot bumper device coupled to a mobile robot for immobilizing the robot when a predetermined external force is sensed and a robotic bumper system for controlling at least one mobile robot located within an assembly area is provided. The robot bumper device includes at least one constant force spring member having a first portion attached to an outer surface of a mobile robot for providing constant absorption of an external force resulting from a collision between the bumper device and an unsuspecting object. A pressure sensitive electronic switch is mounted to a first surface of a substantially planar plastic member that extends across a predetermined length of the mobile robot.
Abstract: The shock-absorbing safety device has lateral protection elements which extend along the sides of a truck. Actuation devices move the lateral protection elements transversely with respect to the truck between a loading position, in which the lateral protection elements are adjacent to the sides of the truck, and a transport position in which the lateral protection elements are spaced therefrom. End protection elements provide, in the transport position, substantial continuity with the lateral protection elements, and control devices detect any collisions transmitted by the lateral protection elements and the end protection elements.

Abstract: A band-like safety bumper for an automatic guided vehicle has a hinge pin rigidly attached at either end with a lever rigidly attached to the pin. A proximity switch is located near the lever and sends control signals to stop the vehicle as a result of obstacle induced movement of the lever.
Abstract: Safety device for forklift trucks comprises a bumper fixed to a telescopic support fitted to the vehicle chassis, the support being able to traverse and rotate to a limited extent in relation to the chassis. The support is connected to equipment designed to activate devices which stop the vehicle if the movements and/or rotations of the support exceed a preset value.
Abstract: A bumper for impact detection with an object is disclosed. An electrically conductive member has a compressible, electrically conductive material mounted thereto. An insulator formed of mesh material is sandwiched between the electrically conductive member and the electrically conductive material for electrically insulating the member and the material when the member is in a non-compressed state and to provide electrical conduction between the member and the material when the conductive material is in a compressed state.
Abstract: The collision protection device comprises a collision protector held in a rest position by spring force. Upon collision against an obstacle, the collision protector is displaced against the spring force and thus cooperates with a de-energizing device. This collision protector is mounted on the vehicle chassis by two swing arms arranged symmetrically non-parallel or in angled relationship to the longitudinal axis of the vehicle. This is to permit the de-energizing device to function effectively, irrespective of the place of impact of the obstacle against the collision protector and irrespective of any deformation of the collision protector. Each swing arm is pivotably mounted on the collision protector and on a sliding link member. Each sliding link member is acted upon by the spring force and is displaceably positioned on a cross-shaft mounted on the vehicle chassis perpendicular to the longitudinal axis of the vehicle.
Abstract: A travelling vehicle equipped with obstacle detector sensors having, at the front of the vehicle body (1), a noncontact-type obstacle detector sensor (A) and a contact-type obstacle detector sensor (B), and a vehicle speed control device (20) adapted to automatically reduce the vehicle speed from a preset vehicle speed (v.sub.)0) to a predetermined vehicle speed (v.sub.1) when the noncontact-type obstacle detector sensor (A) detects an obstacle, adapted to automatically reset the vehicle speed to said preset speed (v.sub.0) when the sensor (A) does not detect the obstacle any more during such speed reduction, and adapted to automatically stop the travelling of the vehicle immediately when the contact-type obstacle detector sensor (B) detects the obstacle.
Abstract: The invention provides a device for activating a passenger restraining system in a vehicle comprising, a dash-pot assembly arranged to be operatively mounted between the vehicle structure and a bumper on the vehicle, the dash-pot assembly including a cylindrical tube, a closure across the tube and a piston movable in the tube to form with the closure a chamber for pressure fluid in the tube, throttle means in communication with said chamber arranged to control exit of pressure fluid from the chamber and to damp movement of the piston relative to the tube whereby to dissipate energy, and a sensor mounted as an assembly with said tube, the sensor including an electrical switch operable in response to fluid pressure in said chamber.

Abstract: This invention provides a safety arrangement for a dumping vehicle which may include a bumper movable to energize a brake actuator, the bumping being retractable upon tilting of the dumping bed. Modified bumper mounting arrangements are provided for various kinds of vehicles. A latching relay may be included to cause the brake actuator to hold the brakes locked, irrespective of disengagement of the obstruction. The bumper may include a pneumatic chamber with a flexible wall, with a pressure-operated switch for operating the brake actuator. Also, an exteriorly actuated switch may be used in a two-man operation in lieu of a bumper.

Abstract: A steering system for motor vehicles, especially for passenger motor vehicles in which parts of the front section are so constructed that they act on parts of the steering linkage in the sense of blocking the steering in case of a displacement of these parts of the front section in the direction toward the passenger space which displacement is caused by a front-end impact or front-end collision.
