Abstract:
A vehicle occupant protection apparatus includes a headrest control unit for drive-controlling a headrest actuating mechanism. This control unit itself predicts that a vehicle behind is about to impact its own vehicle, and controls the headrest actuating mechanism to move a seat headrest forward and thereby reduce the size of the gap between the headrest and the neck of the occupant of the seat.
Abstract:
Arrangement and method for controlling a component in a vehicle in which at least one morphological characteristic of an occupant is measured and a current position of at least a part of a seat on which the occupant is situated is obtained. The component is controlled based on the measured morphological characteristic(s) and the current position of the seat. The component may be an occupant restraint device, such as an airbag whose inflation, deflation and/or deployment direction is/are controlled.
Abstract:
Vehicle seat including a cushion defining a surface adapted to support an occupying item, a spring system arranged underneath the cushion and a sensor arranged in association with the spring system and/or cushion for generating a signal based on downward movement of the cushion caused by occupancy of the seat which is indicative of the weight of the occupying item. The sensor can be a spring retained at both ends and which is tensioned upon downward movement of the cushion whereby a force in the spring indicative of weight of the occupying item is measured. The sensor can also include strain gages, e.g., SAW strain gages.
Abstract:
A head restraint assembly includes a curved support member for upwardly and forwardly deploying a headrest. The support member is selectively locked and unlocked to alternately maintain the headrest in a retracted position or deploy the headrest. A vehicle impact sensor signals the release of the support member when a vehicle impact is sensed. The headrest is deployed quickly and effectively until it reaches its potential full deployment, or until an occupant's head contacts the headrest.
Abstract:
A control system and method for automatically adjusting the position of a headrest of a seat assembly for a vehicle. The control system includes at least one occupancy sensor disposed within the seat assembly for detecting the presence of a passenger in the seat assembly and at least one passenger position sensor disposed proximate to the headrest for detecting the position of a passenger's head relative to the position of the headrest. A control module monitors the output of the at least one occupancy and position sensors and generates a control signal instructing the at least one drive motor to reposition the headrest to adjust to the presence and position of the passenger in the seat.
Abstract:
A motor vehicle seat frame assembly has a headrest movable between an extended position and a retracted position. The frame assembly comprises a seatback frame operatively engaged with the headrest, a cable, and a rod having an extension. The seatback frame is pivotable from a use position to a lowered position, while the cable extends between the headrest and a fixed point. A tensioner is attached to the seatback frame, and is adapted to wind the cable on the extension when the seatback frame is pivoted toward the lowered position.
Abstract:
A system for the displacement of a neck rest in response to the displacement of a vehicle seat in an automobile, wherein the neck rest is mounted to a first structural part which is height-displaceably mounted to a second structural part, the latter being fixedly secured to the rest of the seat, the system having the following features: a rope defining a loop to transfer a force along the loop, one section of the rope being connected to the first structural part, the rope being guided about two spaced idle rollers, one of the rollers being rotatably supported by the seat and the other by the second structural part a first coupling part fixedly connected to the rope a second coupling part fixedly connected to the vehicle a coupling element movably supported on the seat and selectively engageable with the first coupling part actuating means for the coupling element on the seat adapted to coact with the second coupling part in response to the position of the seat such that in a forward position and upon displacement of the seat from the forward towards the rear position along a predetermined path or upon displacement of the seat from a rear position towards the forward position after a predetermined path the second coupling part coacts with the actuating means such that the coupling element is positively connected to the first coupling part and the second coupling part and locking means which lock the first coupling part when the coupling element is in disengagement with the first coupling part.
Abstract:
System and method for analyzing motion of occupants of the vehicle in which a wave-receiving system receives waves from spaces above seats of the vehicle in which the occupants would normally be situated and a processor coupled to the wave-receiving system determines movement of any occupants based on the received waves. The wave-receiving system may be arranged on a rear view mirror, in a headliner, roof, ceiling or windshield header, in an A-Pillar or B-Pillar, above a top surface of an instrument panel, and in connection with a steering wheel or an airbag module. The processor can be programmed to determine the location of the head, chest and/or torso of any occupants. If it determines the location of the head of any occupants, it could monitor the position thereof to determine whether the occupant is falling asleep or becoming incapacitated.
Abstract:
Arrangement and method for controlling audio reception by occupants of a vehicle in which the position of any occupants is determined and the entertainment system controlled to provide specific sound for the occupants based on the determined positions of the occupants. Sound generating components of the entertainment system are automatically adjustable based on the determined position of the occupants. A hypersonic sound generating system may be used wherein ultrasonic frequency generators generate ultrasonic waves which mix with ultrasonic waves generated by another ultrasonic frequency generator to thereby cause the creation of new audio frequencies in an area determined based on the position of the occupants. In addition, the presence and direction of unwanted noise may be detected and sound created to cancel the unwanted noise in the area including the determined positions of any occupants.
Abstract:
Apparatus for disabling an airbag system for a seating position within a motor vehicle in which occupant sensors are situated adjacent or on a roof above the seat and the presence or absence of an occupant of the seating position is detected using the occupant sensor(s). The airbag system is disabled if the seating position is unoccupied. The position of an occupant is detected if the seating position is occupied and the airbag system is disabled if the occupant's position would result in injury to the occupant greater than any injury resulting from non-deployment. Further, the airbag deployment parameters, e.g., rate of inflation and time of deployment, may be modified based on the occupant's position to adjust inflation of the airbag according to proximity of the occupant to the airbag door.
