Abstract: A supplemental passive safety apparatus is provided which benefits known technology for detecting traffic emergencies. The apparatus may contain a movable rectangular frustum which interacts with rigid crossbars to control middle pivot joints responsible for adjusting location of horizontal support bottom panels with a cushion. An alternative apparatus may contain a rope traveling through a double flanged wheel mounting to a pneumatic cylinder instead of a rigid crossbar interacting with a movable rectangular frustum. Simultaneously with an opening of an automatic valve, compressed air is transmitted from a cartridge to a pneumatic cylinder causing a piston with rod to move toward a front crossbar. The rigid crossbar in one version or rope in an alternative version release a pivot joint controlling location of horizontal support bottom seat panels with cushion.

Abstract: An apparatus or front row vehicle seat having portions A, B, C and D. The apparatus is adjustable by an occupant in its normal motionless position. When a vehicle electronic control unit senses a hazardous traffic situation, it causes activation of a seat actuator. In response, each of seat portions A, B, C, and D is simultaneously altered, without an occupants' action, to a new deployed position. The new deployed positions of the seat portions A, B, C, and D inhibit occupant ejection from a vehicle. The portions A, B and D of the apparatus are supported by front and rear stationary pillars and a middle movable pillar. The pillars project from a related unit seat height adjuster. The interaction of the rear stationary pillars with the portion D helps keep various seat components in the same orientation and position with respect to each other before and after deployment.

Abstract: A vehicle safety seat (104, 202, 302, 502, 802) includes a seat bottom (120, 210, 310, 504, 810) that is movable substantially instantly from a substantially horizontal normal orientation for normal traveling to a deployed angled orientation contemporaneously with a vehicle crash. The deployed safety seat shifts a seat occupant (102) into a protective posture to reduce accelerations, loads and moments of force on various parts of the occupant's body. In preferred embodiments, the seat bottom is deployed into its angled orientation by lowering the rear (124, 312, 507, 812) of the seat bottom, causing the seat bottom to pivot about a front pivot (174, 220, 320, 518, 820) at the front of the seat bottom. Typically, a vehicle safety seat includes a backrest (130, 240, 360, 550, 840). In some embodiments, a backrest (130, 240, 360, 550) is movable downwards and/or rearwards simultaneously with movement of the seat bottom.

Abstract: The mechatronic vehicle safety seat described transforms the geometry of the bottom frame and backrest frame associated with a head restraint when a collision is imminent. On a signal from a pre-crash detection device, or a manual or verbal indication, an energized solenoid instantly releases the forces of torsion springs and triggers the seat bottom and backrest for concurrent movement in sufficient time to mitigate excessive accelerations, loads and moments of forces acting upon seated occupants in response to impact modes. The distorted geometry of the bottom frame and backrest with head restraint enhances the safety performance of the seat belt and reduces the aggressiveness of airbags.

Abstract: A collapsible vehicle safety seat is essentially designed to restrain movement of the occupant especially at the time of frontal, rear-end and lateral collisions in high and low speed or when an impact becomes inevitable. The seat includes an actuator controlled and operated electronically or manually. The onset of the collision sequences the car crash sensor or collision avoidance devices including occupant voice activated actuator. The trigger release forces of a biasing member or equivalently devices electromagnetic or pyrotechnic to deploys instantly pivot frame incorporated with movable seat cushion, seat back and headrest. The alteration of the movable seat assembly from a normal stationary position creates a safety zone that allows occupants to lower their center of gravity to an optimum seating position.

Abstract: A multifunction vehicle seat reduces the impact peak and decreases the transfer of acceleration and deceleration forces to all regions of the occupant's body during frontal, rear-end and lateral collisions at high and low speed impacts or when collision becomes inevitable. The seat is isolated from the structural integrity of the vehicle by an anti-friction ball and a plurality of stabilizers. The anti-friction ball is adapted for universal movement over a movable base plate to reduce the transfer of kinetic energy to the seat and to the occupant. The stabilizers are interlocked and engaged with the seat support assembly to delay the response of the seat to the impact until a pulley system is activated. The pulley system is activated electronically or manually to deform the seat cushion, seat back and headrest during and before impact.

Abstract: A vehicle seat apparatus for absorbing different types of forces, shocks, and vibrations commonly encountered in different types of vehicle accidents and sudden hard braking of a vehicle. The vehicle seat apparatus includes a seat cushion, a seat back cushion, a bottom support structure, a top plate, a ball bearing housing containing a plurality of ball bearings, a plurality of shock absorbers, a plurality of linkage rods, and a pulley system. The top plate is adapted for sliding over the ball bearings in a lateral, forward, and/or rearward direction in response to a vehicle accident or to a sudden hard braking of the vehicle. The vehicle seat apparatus may further include at least one seat restraint and at least two lateral side air bags.

Abstract: A safety system for dissipating the forces involved in a vehicle collision comprises two large friction platforms beneath the vehicle unibody or floor pan, with each platform having an actuator between the platform and the overlying vehicle structure and connected to the platform by a series of struts or arms. The actuators are preferably automated and pyrotechnically actuated to drive the struts outwardly and downwardly, thereby driving the platforms downwardly beneath the vehicle and against the underlying surface to lift the vehicle slightly above the underlying surface. The vehicle may be surrounded by a plurality of bumper-like impact absorbing contact structures, with each structure also linked to a corresponding friction platform. The outer portion of each contact structure telescopes into the inner portion, and drives a series of struts connected to the corresponding friction platform.
