At head on collision a switch at length of the front bumper activates two electromagnets pulling retaining pin, from the steel framed nylon sheet on the car ceiling, hinged over the windshield frame with the help of two springs brings it down in between the occupant and the windshield, but holding back in perpendicular position by two nylon ribbons, the device preventing with its strength and resilience the occupants head from windshield head injuries. Presently used seat belt can be still used,...

A sonar detector system for exiting passengers on public conveyances such as buses and trolleys which detects the presence of passengers at unattended exits and opens the exit doors is disclosed. The system employs two sonar transducers/receivers at each door of the exit with narrow, electronically truncated detection zones. The sensors are positioned so as to prevent operation of the doors due to echoes from passengers on the aisle floor of the public conveyance or receipt of echoes from outsid...

The invention concerns a lighter-than-air craft for transporting by air equipment and passengers, more particularly, it concerns an aircraft whereof the frame (1) made of light metal and erected vertically, contains and protects the passenger compartment (4) of the invention, and all the components of the invention which, by a mass-reducing assembly (2-8-9-11-19), uses light gas power for neutralizing the earth's gravitational pull. Electric motors actuating propellers (6-7) with multiple blades...

There is provided apparatus for determining the number of passengers entering and/or leaving a collective passenger vehicle. The apparatus comprises means for projecting a pair of light-beams of invisible light across the passageway of said passengers and means for receiving said light-beams. Detecting means which operate in conjunction with the light-beam receiving means are adapted to detect the energized or unenergized state of the receiving means and in response thereto to feed information t...

A safety arrangement for passengers of a moving vehicle includes an inflatable air cushion for maintaining passengers in their seat positions and a plurality of gas generators for inflating the cushion. The cushion is inflatable at different rates depending on vehicle deceleration by the employment of an electrical release circuit. The circuit includes a piezoelectric sensor for providing a signal representative of deceleration, a first threshold value switch, an integrator, a plurality of thres...

A safety device for a vehicle occupant comprising a restraint for the vehicle occupant, a sensing circuit for evaluating a vehicle condition, a control circuit for actuating the restraint in response to a predetermined vehicle condition, and two separate reserve energy storages for supplying electrical energy to the sensing and control circuits, respectively.

An electrically powered vehicle transportation system utilizes a guideway with parallel enclosed rails. Each enclosed rail has an electrical bus bar for supplying power to vehicles on the guideway. The guideway will accommodate dual-mode vehicles that are capable of usage on conventional streets as well as on the guideway. The guideway also accommodates conventional vehicles and ferries that operate only on the guideway. The dual-mode vehicle has a body with axles that are extensible. The axles ...

A retention mechanism for the passengers of motor vehicles which is able to deflect in the load direction when reaching a predetermined load, preferably under energy absorption; the deflection movement of the retention mechanism is thereby transmitted to the seat backrest in the sense that the coordinated seat backrest yields in the backward direction.

A cableway cabin especially for a gondola lift has an asymmetrical shape with reference to the vertical median plane extending in the direction of travel of the cabin. The width of the inner lateral side of the cabin, which faces the inner side of the curve when the cabin travels on the half-loop circuit, is smaller than the width of the opposite lateral side. Two benches are disposed against the front and the rear sides of the cabin and the space between the two passengers seated near the inner...

The food conveyor will be used on passenger planes with the capacity to hold over 30 people and will consist on a continuous conveyor-carrousel localized in the passenger compartment of the plane on each side of the aisle and suspended from the ceiling. It is controlled by one of the attendants from the kitchen area where the motor is located which makes the conveyor to circulate in order to carry and to deliver the feeding and empty trays, beverages, etc. around to the passengers thus making th...
