A seat assembly includes a cushioned component having a lattice matrix, wherein the lattice matrix includes a first portion defined by a first pattern of interconnected links which defines a first set of cells, and a second portion defined by a second pattern of interconnected links which defines a second set of cells. The first portion of the lattice matrix includes a density profile that is different than a density profile of the second portion of the lattice matrix. An air bladder is disposed within a core portion of the lattice matrix and includes a non-porous outer casing surrounding an interior cavity. The outer casing of the air bladder and the lattice matrix are integrated components comprised of a common material to define a monolithic structure created using an additive manufacturing process.

A method controls drive units for adjusting vehicle seat components. According to the method, a vehicle speed-dependent and crash-related nominal position or a vehicle speed-dependent and crash-related nominal position range are defined for at least one component. Starting from an actual position that is the same as the nominal position or from an actual position within the nominal position range, the actual position cannot be manually or automatically adjusted in the first instance or can only be adjusted in the nominal position range in the second instance, independently from the identification of a crash situation. Starting from an actual position that is different from the nominal position or outside the nominal position range, the actual position is automatically adjusted towards the nominal position or the nominal position range, preferably according to the identified defined situations, independently from the identification of a crash situation.

A seat base for a vehicle seat includes: two seat base side flanges; a seat base front flange rotatably mounted with respect to the two seat base side flanges; and a mechanism for adjusting the orientation of the front flange relative to the side flanges. The mechanism includes: two connecting rods, each connecting rod being connected to one of the side flanges; a tube extending between the two connecting rods; and at least one clip attached to the front flange and having a baseplate and two branches extending from the baseplate to form a receiving space wherein a portion of the tube is received; each clip further having at least one tie arranged between the baseplate and one of the branches. The baseplate, the two branches, and each tie are integral with each other.

A transportation system is disclosed. The transportation system includes a vehicle, a plurality of seating assemblies positioned within a passenger compartment of the vehicle and defining an arrangement, a plurality of actuators that effect movement of various components of the plurality of seating assemblies, a plurality of sensors, and a controller. Specific examples of pre-set or pre-programmed arrangements are disclosed, as well as the ability to customize the arrangement. Additionally, exemplary methods are disclosed that illustrate transitions between a variety of the pre-set or pre-programmed arrangements.

A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

A seat assembly may include a seat having a seat base and a seat back, a temperature control unit disposed at least partially in the seat back, and/or an ECU connected with the temperature control unit. The ECU may be configured to receive an input related to (i) a first state corresponding to symptoms and/or discomfort associated with dysmenorrhea and/or (ii) a second state corresponding to symptoms and/or discomfort associated with sciatica. The ECU may be configured to operate the seat assembly according, at least in part, to the input.

Provided is a vehicle seat having a variable cushion length. The vehicle seat includes: a front panel of metal arranged on a front-end side of a seat cushion to form a frame of the seat cushion; a sliding device allowing a movable portion to be displaceable and including a sliding member of resin displaceable relative to the front panel in seat front-rear directions; and a bracket of metal that is coupled to the front panel in a manner displaceable relative to the front panel in the seat front-rear directions and that is displaced integrally with the sliding member, the bracket transmitting a load acting on the movable portion to the front panel.
