A navigation instrument for roadway vehicles comprises a first counter for counting pulses each occurring in response to the vehicle moving a predetermined distance to detect the distance travelled from the starting point of a trip, a second counter for counting clock pulses to detect the time elapsed from the start of the vehicle. A microcomputer or digital circuitry is provided to compute on the data received from the first and second counters to derive an output data representative of the average speed of the vehicle over the distance so far travelled and to compare the computed average speed with a desired speed to detect the deviation of the actual average speed from the reference. A comparator is provided to detect when this deviation exceeds a predetermined value to generate a warning signal to alert the vehicle driver to correct the vehicle speed.

A cylinder-piston assembly of a gas-operated actuator for straining a seat belt when a vehicle encounters a collision is provided with gas passageways which are normally closed by a valve. The valve permits gas to escape through the passageways when the gas pressure exceeds a predetermined value due to pulling of the piston against the force developed by the gas during forward motion of the seat occupant so that the occupant may be secured to the seat with a restricted force and adequate energy absorption.

A pinion and upper and lower internal gears are adapted to be subassembled to a hub portion of a steering wheel prior to mounting on a steering shaft. An anchor leg is provided to the lower end of the lower internal gear and has a pair of opposed lateral sides which are opposed in the lateral direction perpendicular to the diametrical direction of the lower internal gear. A location arm is provided to the upper end of a stationary column and has a bifurcated upper end to loosely receive therewithin the anchor leg. The bifurcated end of the location arm is resiliently deformed by a screw driven thereinto to contact the lateral opposed sides of the anchor leg.

A passive seat belt system includes a mechanical linkage between the seat back and a guide member which holds the belt in an appropriate operating position. The linkage serves to move the guide member forward as the seat back is tilted forward, to move the guide member to its normal working position when the seat back is moved to its normal upright position, and to hold the guide member in its working position as the seat back is tilted backwards. The mechanical linkage includes a linkage lever, of which one end is pivotably attached to the seat back and the another end constitutes a contoured lost-motion linkage engaging the pivotable guide member. The lost-motion linkage is designed to actuate movement of the guide member when the seat back moves within the forward moiety of its reclining range, and to be only slackly engaged with the guide member when the seat back is moved in the portion of its reclining range rearward of its normal upright position. A stop holds the guide member in its working position in the latter case.

A safety seat belt arrangement for protecting an automotive seat occupant. According to the present invention, there is provided a safety seat belt arrangement which comprises, in addition to a first belt having a shoulder harness portion the end of which linked with a rear upper end of a door and a lap harness portion the end of which linked with a rear lower end of the door and a second belt one end held by a safety seat belt retractor and the other end linked with the first belt through a linkage ring, a projecting member located at an outboard side of the seat projecting by means of an elastic means, so as to be pushed by the door when the door is closed, an arm assembly located at the inboard side of the seat and rotatably fixed on a seat frame bracket for supporting the second belt, and a linkage member located at the rear of the seat for connecting the projecting member and the arm assembly so that the arm assembly stands upright to release the first belt from the body of the occupant when the door is closed and the projecting member is pushed, whereby the force required to open the door can be remarkably reduced.

A door for an automobile disclosed herein comprises a glass run rubber embraced in a door frame for guiding a window glass, the glass run rubber formed with a channel for receiving a wire harness extending from a buckle for releasing a seat belt in an emergency to a belt wearing alarm device for warning with a signal a driver of a disconnection of the seat belt to the buckle, thereby eliminating a notch formed in the door frame which would reduce the rigidity of the door, preventing the wire harness from being cut by an edge of a notch formed in the door frame and eliminating extra parts for retaining the wire harness in the channel.

A knee protector for use in a passenger car equipped with an instrument panel and a steering column installed near the instrument panel, comprises a first and second panels which are separate to each other. The steering column is positioned between the first and second panels. The first and second panels are attached under the instrument panel. A pad covering the first and second panels. The pad has a convex portion to be inserted into a space between the first and second panels.
摘要:
A section of a shock absorbing member, which is located in the vicinity of a hard projection, has higher stiffness than another section of the same which is located in the distance from the hard projection, so that when the occupant's knee portion is forced to move toward the hard projection and collides with the shock absorbing member upon vehicle collision, the knee portion under movement is forced to turn in a lateral direction, that is toward the low stiffness or safety section of the member, losing its kinetic energy.

A navigation information announcing system for a motor vehicle comprises a tape player, circuitry for measuring the distance actually travelled by the vehicle, circuitry for reproducing distance information pre-recorded on a magnetic tape, and a comparator. A distance indicated by a reproduced datum from a magnetic tape is compared with the distance actually travelled so that the tape player performs a pause operation until the two distances equal each other. When these distances equal each other, the normal playback operation is reestablished so as to reproduce oral information pre-recorded on the magnetic tape, supplying the vehicle driver with directional information.

An apparatus for adjusting the position and/or angle of each movable equipment of a motor vehicle comprises sensors to produce electrical signals indicative of the position and/or angle of each movable equipment, memory circuit including a plurality of memory units for respectively storing sensed information indicative of the optimal positions and/or angles of the equipment for each driver, comparators responsive to the sensed information and the stored information, and driving circuitry responsive to output signals of the comparators to adjust the positions and/or angles of the equipment. When the drivers are changed, the sensed information is compared with the stored information and then the position and/or angle of each equipment is adjusted until the sensed information equals the stored information to provide the driver with the optimal position and/or angle.
