  • Patent number: 11628749
    Abstract: A vehicle seat for a motor vehicle includes a seat bottom and a seatback displaceable relative to one another. A seat positioning system has an actuator for displacing one of the seat bottom and the seatback toward the other of the seat bottom and the seatback. The system further includes a position sensor for generating a seat position signal indicative of a position of one of the seat bottom and the seatback relative to the other of the seat bottom and the seatback. The system further includes a controller for generating an activation signal in response to the controller determining that the position is above the position threshold. The actuator displaces one of the seat bottom and the seatback toward the other of the seat bottom and the seatback in response to the actuator receiving the activation signal from the controller.

  • Patent number: 11022531
    Abstract: A seat belt test apparatus for testing a safety restraint system for a vehicle comprises a first, a second, and a third test stand, an impactor apparatus, and a resistor apparatus. The first, a second, and a third test stand are selectively fixed to a test bench. The first, second and third test stands each comprises a pulley disposed proximate a top end of each of the first, second, and third test stand. The first test stand further comprises a first pretensioner mount. The third test stand further comprises a second pretensioner mount.

  • Patent number: 8707757
    Abstract: A test apparatus collects performance data for a seat belt system having components providing operating stages of pre-tensioning, locking, and load limiting of the seat belt. A bench plate mounts the components of the seat belt system and includes first and second pulleys spaced apart on the bench plate and having the seat belt extending horizontally therebetween. At least one load sensor senses the load experienced by the seat belt. A resistor engages the seat belt between the first and second pulleys and pulls downwardly to introduce slack in the seat belt. An impactor mass is suspended above the seat belt and is released to free-fall onto the seat belt and impose a load on the seat belt simulating the load of a seated occupant being imposed on the seat belt. A control module energizes the pre-tensioning stage and a plotter records force versus time performance data.

  • Publication number: 20090126114
    Abstract: A mobilization handrail (1, 2) which is controlled by a patient without the need for help of medical staff, includes an elongated profile (5). The elongated profile (5) is placed in a guide (4) for inserting and drawing-out of the elongated profile (5) into and from the space underneath the loading surface of the bed (3) while the elongated profile (5) is arranged for positioning in a substantially vertical position after its drawing-out from the space under the loading surface of the bed (3), and it is equipped with a locking device (13) for stabilization in this position.
