A vehicle seat includes a pad configured to support a body of a seated occupant. The pad has a transverse air passage extending in a direction along a back surface of the pad and a plurality of longitudinal air passages each having one end connecting with the transverse air passage and the other end open to a front surface of the pad. The transverse air passage has a first transverse air passage connecting an air introduction hole from a fan or an air discharge hole to the fan and the longitudinal air passage directly with each other, and a second transverse air passage connecting the air introduction hole or the air discharge hole and the longitudinal air passage with each other via a resistant body having a resistance against an air flow.

A vehicle seat capable of efficiently utilizing air delivered from an air conditioning device and thereby adjusting the temperature of heat generated by a seat heater is described. A vehicle seat comprises a seat heater between a cushion pad and a surface skin. A heater wire affixed to a seat base material of the seat heater is disposed at a position to partially overlap air passages formed on the cushion pad. Moreover, the heater wire is formed on the seat base material, is disposed at a position to partially overlap a plurality of through-holes having a greater width than the heater wire, and extends while avoiding center portions of the through-holes.

Provided is a cable holder including a strap arranged in parallel with any one of a wire inserted into a car seat or a cable inserted into the seat, a fastening device which integrally couples the strap with one of the wire or the cable, and a tie which is coupled with the strap and coupled with another one of the wire or the cable.

The seat comprises a padded body (2) and at least one heating element (4), and also at least one cavity (3) in said padded body (2), in the interior of which said at least one heating element (4) is arranged. The assembly method comprises the stages of forming at least one cavity (3) in said padded body (2); and arranging said at least one heating element (4) in the interior of said at least one cavity (3). It makes it possible to enhance the positioning accuracy of the heating elements and enables greater speed of execution.

A capacitive detection system for detecting occupancy of a vehicle seat includes a signal generating unit and a signal evaluation unit. The vehicle seat has a seat heater member configured for receiving time-varying output signals of the signal generating unit. The signal evaluation unit is configured to generate an output signal that is indicative of the seat heater member to be defective, if the sensed capacitance of the seat heater member is less than a second predetermined threshold value for the sensed capacitance.

A vehicle seat including a seat pad including a flow channel portion, a seat cover covering the seat pad and having breathability, a functional member disposed between the seat pad and the seat cover and having breathability, and a blowing member configured to blow the gas into or out of the seat through the flow channel portion of the seat pad and the seat cover along a flow path, wherein the functional member is integrated with any one of the seat pad and the seat cover with an adhesive portion, which has poorer breathability than the seat cover and the functional member, interposed therebetween, and wherein the adhesive portion includes a passage portion through which the gas is configured to pass, and the passage portion is disposed in the flow path of the gas.

A distributed control system for a vehicle seat includes a control module for communicating on a single communication bus and a plurality of nodes connected to the control module via the communication bus, wherein each of the plurality of nodes are associated with a load device and each of the plurality of nodes comprises a logic component specific to the load device.

A device, such as a heated seat cushion device, is provided. Circuitry and other components are used to regulate, control and/or switch electrical power to an electrical element, such as a heating element, of the device. The device may regulate the energy delivered to the electrical element by a processor on an intelligent energy management platform. Accordingly, power may be routed to the electrical element of the heated device in a controlled manner. Control may include turning on and off the power, providing pulsed power, and modulating the power and/or pulsed power delivered to the electrical element.

A vehicle seat assembly in which an impervious insert (41, 141) including a heating element and having a plurality of channels (42, 142) extending from an aperture (44, 144) positioned on a first side of at least one of a seat cushion (22) and a seat back (124) and in which a ventilation system (60) is coupled to a second side of the at least one of the seat cushion and the seat back for drawing air along the plurality of channels through the aperture and through a hole (30, 130) in the seat cushion or seat back for controlling the temperature of the seat assembly.

A capacitive sensor for a vehicle seat comprises an antenna electrode and a control and evaluation circuit operatively connected to the antenna electrode. The control and evaluation circuit is configured to operate in a first mode of operation, during which it measures alternating electrical current flowing between the antenna electrode and ground. The capacitive sensor comprises a seat frame connector for connecting the control and evaluation circuit to the seat frame of the vehicle seat. The control and evaluation circuit is configured to operate in a second mode of operation, during which it measures electrical current flowing into the seat frame connector.
