  • Patent number: 10906443
    Abstract: An actuating device for releasing a locked release and/or adjustment mechanism of a vehicle seat having a first and a second actuating element. Provision is made that the first and second actuating elements and an indicator element are arranged together in a housing of the actuating device. The actuating elements are connected to at least one actuating mechanism that provides for a release of the locked release and/or adjustment mechanism upon actuation of one of the actuating elements. The actuation of one of the actuating elements substantially simultaneously results in an actuation and indication of the indicator element concerning the released or locked state of the release and/or adjustment mechanism.

  • Patent number: 10756921
    Abstract: Systems and methods for training network-connected objects to provide configurations in association with events within media assets. A respective configuration setting of a network-connected object and a baseline biometric state of a user may be stored in a database for each event within a media asset. An event within a media asset (for display) may be detected. In response, a command may be sent to the network-connected object to implement the respective configuration setting. A determination may be made whether the user adjusts the respective configuration setting to a new configuration setting within a predefined time of the event. A biometric state of the user may be retrieved from a biometric device in response to the adjustment to a new configuration setting. If the biometric state does not correspond to the baseline biometric state, the respective configuration setting may be replaced with the new configuration setting.

  • Patent number: 10449100
    Abstract: A seat on a lift assist chair pivots between a lowered position in which a user can sit in the chair, and a raised position in which a seated user is helped out of the chair and into a standing position. A pair of arms is operatively attached to the seat. Responsive to the application of a user-applied downward force, the arms pivot about an axis thereby causing the seat to pivot between the lowered position and the raised position. First and second counterweights are also connected to the arms, and are axially adjustable relative to the axis about which the arms pivot. This movement permits the user to selectively alter the moment of the pivotable arms.

  • Patent number: 9668928
    Abstract: A chair includes a backrest that pivots with respect to the seat in a manner that improves the occupant's experience during the transition from an upright position to a reclined position. During pivoting of the backrest with respect to the seat, the backrest moves in a manner having an instantaneous center of rotation that does not remain stationary during the pivoting of the backrest. In some embodiments, the instantaneous center of rotation begins at a location lower than a height of the seat and moves backward as the backrest pivots from the upright position to the reclined position. The movement of the instantaneous center of rotation follows a smoothly curved path that has a continuous first derivative and, in some embodiments, continuous higher order derivatives as well. The movement may be effectuated via pins coupled to the backrest that ride in smoothly curved channels defined in a seat frame.

  • Patent number: 8496294
    Abstract: A seat assembly for supporting an occupant above a floor includes a support mechanism operatively coupled between a seat back and a seat cushion. A rear end of the seat cushion is released from the support mechanism to pivot the seat cushion from a generally horizontal position to a generally vertical position in response to pivotal movement of the seat back from an upright seating position to a forwardly folded position. The support mechanism is released from the floor and a stand-up link pivotally coupled between the floor and the support mechanism moves the seat cushion from the generally horizontal position to the generally vertical position and simultaneously urges the seat back to pivot relative to the seat cushion, thereby maintaining the seat back in a generally vertical orientation defining a stand-up position.

  • Patent number: 8474910
    Abstract: A vehicle seat includes a base (9) which includes at least one front foot (11). A seat (3) is connected in an articulated manner to the front foot by at least one front leg (13). At least one rear foot (21) is locked to the base (9) in at least one use position. At least one coupling (42) is provided between the seat and the rear foot. At least one coupler (30) is provided between the backrest and the coupling or the seat. The seat may be transferred from the use position into a boarding position as, after unlocking the rear foot, the seat pivots upwards and the backrest carries out a forward shifting movement by means of the rear foot. The seat may also be transferred from the use position into a flat-floor position, by the backrest pivoting forward and the seat being lowered by the coupler.

  • Patent number: 8434822
    Abstract: A device for an adjustable piece of seating and reclining furniture with an adjustable angle between the seat and the back of the piece of furniture, wherein on each side of the piece of furniture there is located a fitting projecting upwards from its base, the seat being tiltable about a forward suspension point on the fitting, and the back being tiltable about a rear suspension point on the fitting, wherein the back upon tilting backwards causes the seat to tilt backwards in that a link is pivotally fastened to a rear part of the seat frame and pivotally fastened to a lower part of the back frame, the pivotal connection of the link to the back frame being located behind and below said rear suspension point. On an increase in the angle between the seat and the back, the angle that the neck rest of the piece of furniture forms with the back is reduced.

Furthermore, a first lever parallelogram (27) is provided in order to maintain the backrest (19) upright in any position. The backrest (19) can be displaced by the first lever parallelogram (27) by means of a rod (30), in order to ensure that no undesirable relative movement occurs between the backrest (19) and the back of the user when getting up or sitting down. A second lever parallelogram (29) controls the movement of the seat (17) when getting up and sitting down to ensure that no relative movement develops between the seat (17) and buttocks of the user. The stand-up unit may be provided with a base to serve as a chair, particularly a therapy chair. The stand-up unit, however, may also serve as a stand-up wheelchair, when connected to an undercarriage.

  • Patent number: 8388065
    Abstract: A vehicle seat movable between a seating mode, an ingress/egress mode, and a cargo mode includes a vehicle seat rotation controlling apparatus. The vehicle seat rotation controlling apparatus allows a seat back to be rotated toward a seat bottom into the ingress/egress mode while holding the seat bottom in an elevated position. Further, the vehicle seat rotation controlling apparatus allows the seat back to be rotated further toward the seat bottom into the cargo mode while rotating the seat bottom into a lowered position. When the vehicle seat is moved from the cargo mode to the seating mode, the seat back is rotated away from the seat bottom while the vehicle seat rotation controlling apparatus causes the seat bottom to rotate into the elevated position.

  • Patent number: 8272692
    Abstract: A chair that includes a support module, a seat carrier, an initially forwardly declined seat member articulated to the seat carrier such as by being pivotal along a front, and an initially rearwardly angled backrest carrier having a backrest member, the carrier articulated to the seat carrier such as by being pivotal along a lower end. The angular positions of the seat and backrest member are largely controlled via an actuator arm and adjustable spring arrangement, wherein the actuator arm directly links the seat member to the backrest carrier and the spring arrangement returns the backrest carrier and seat member to initial positions when a weighted load is lessened or removed from the rear of the seat member. A pneumatic cylinder to provide resistance to the seat member, a limiter to limit a maximum and minimum angular position of the seat member, adjustable arm rests, and casters may be included.
