摘要:
A method and system for determining whether a seatbelt of a vehicle is fastened is provided. The system may be configured to detect markers on a seatbelt, engage seatbelt tensioners, and determine whether the markers have moved. The system may then be configured to determine whether the seatbelt is fastened based on movement of the markers.
摘要:
A system for detecting seatbelt positioning includes: a seatbelt having a plurality of stripes extending lengthwise along a length of the seatbelt longer than an entire width of the seatbelt. The plurality of stripes are arranged in an alternating pattern of bright and dark in near-infrared, each having a width in a direction perpendicular to a lengthwise dimension of the seatbelt. The plurality of stripes may include at least two bright stripes and at least two dark stripes, and the widths of the stripes may define an asymmetric pattern with at least one of: two bright stripes having different widths, or two dark stripes having different widths.

Disclosed are embodiments of passenger seats equipped with seat belts for mitigating seat damage and spinal tension from free-flail movements. In embodiments, the assembly includes a seat back, a first slip ring positioned proximate a top of the seat back, a second slip ring positioned lower on the seat back, a retractor, and a webbing threaded through each of the first and second slip rings. During normal use of the seat the first slip ring forms a first pivot for the webbing, and during a qualifying deceleration event the second slip ring forms a new pivot for the webbing lower on the seat back. In a further embodiment, first and second webbings form primary and auxiliary restraints guided by respective first and second pivots.

A pre-collision system for an occupant protection system of a vehicle, includes a predictive sensor system, a vehicle seat, a restraint system, and an evaluation and control unit that evaluates output signals of the predictive sensor system and activates a belt tensioning function of the restraint system if the evaluation of the output signals indicates an imminent collision, where the belt tensioning function generates a tensile force in the belt, which presses a corresponding occupant into the vehicle seat, with a resulting kinetic energy of the occupant that releases a pre-trigger mechanism, which is integrated into a mounting of the vehicle seat, and that enables a blocked degree of freedom of the vehicle seat so that the entire vehicle seat tilts about a defined tilt axis in the direction of an expected impact force.

A seatbelt system may include a seatbelt configured to constrain a waist and a torso of an occupant. The seatbelt may also include a coupling configured to selectively couple a portion of a vehicle and the seatbelt to one another. The system may also include a reel configured to receive at least a portion of the seatbelt, and a tension sensor associated with the coupling and/or the seatbelt and configured to generate a signal indicative of tension in the seatbelt. The system may also include a deployment sensor associated with the seatbelt and configured to generate a signal indicative of a length of the seatbelt deployed from the reel. The system may also include an occupant detector configured to determine, based at least in part on the signals indicative of tension and the length, whether an occupant is properly wearing the seatbelt, such that the seatbelt constrains the occupant.
摘要:
A seat safety apparatus, comprising a lap harness including a lap harness belt segment and at least one lap harness sensor connected with the lap harness belt segment; the lap harness sensor formed of an electrically conductive material having an electrical resistance variable as a function of strain of the lap harness sensor wherein, in response to a change in strain of the electrically conductive material of the lap harness sensor, the electrical resistance of the electrically conductive material of the lap harness sensor changes; wherein the electrically conductive material of the lap harness sensor provides an electrical resistance in an electrical circuit of the seat safety apparatus; and wherein, in response to electrical power provided to the electrical circuit, the lap harness sensor provides a lap harness sensor output which changes as the electrical resistance of the electrically conductive material of the lap harness sensor changes.
摘要:
A multi-point safety belt system is provided with a tension sensor that opens and closes a switch to send a signal indicating the force securing a seat occupant secured by the safety belt system.

Systems and methods for monitoring child seats and children in child seats through sensors paired with a central processing hub which in turn relays notifications of conditions to caregivers or other users based on a notification hierarchy and the urgency of the conditions detected.
摘要:
A front passenger airbag (5) is described for arrangement in the instrument panel (20) of a motor vehicle. It has an airbag envelope (10) having an impact area (11) and lateral surfaces extending from the impact area (11). In order to use small gas generators and to reduce the danger for a passenger in a non-standard seating position, the impact area (11) is nearly exclusively allocated to the front passenger's (I) head or head and shoulder area, the impact area (11) having a concave shape when the airbag envelope (10) is fully expanded and free of external forces, such that a left and right section of the impact area (11) respectively extend farther into the interior of the motor vehicle than a central section.
