A ventilation and massage device for a seat, may include a seat foam pad including a plurality of air discharge holes formed in the seat foam; an air distribution duct mounted in a space in a rear surface of the seat foam pad and fluidically-connected to the plurality of air discharge holes, the air distribution duct being configured to distribute air to the air discharge holes; massage units mounted on a bottom surface of the air distribution duct, the massage units being configured to move forwards and backwards to open or close the air discharge holes or penetrate the air discharge holes; and a controller electrically connected to the massage units and configured to control an amount of movement of the massage units based on information related to a body pressure of an occupant accommodated in the seat and information related to a temperature and humidity at a contact portion between the occupant and the seat.

A passenger seat for commercial vehicles and rail systems, having at least: a massage pad for increasing the ergonomics in the waist section of the passenger and applying massage; a compressor for inflating the massage pad; cooling pads for cooling the passenger; a heating pad for heating the upper portion of the seat and the backrest contacting the passenger; a presence sensor for determining whether there is a passenger on the passenger seat; a belt sensor for determining whether the passenger fastens the safety belt; a wireless charging unit for the passenger to charge a mobile device without using a connection cable; a manual control panel for the heating pad, cooling pad and the massage pad; a wireless connection module for the heating pad, cooling pad and the massage pad; and a control unit where the data collected from the presence sensor and belt sensor are transmitted.

A thermal system for a vehicle seat. The thermal system includes a seat insert; a connector having a first portion at least partially located within the seat insert; and an air mover connected to the seat insert via the connector. The air mover is adapted to generate an air flow within the insert. The first portion of the connector includes one or more air directors within the insert that are configured to change a direction of the air flow within the insert.

A vehicle seat includes: a chamber in which at least a seat-front-surface side is covered with a pad and which circulates the air blown from a front surface of a seat through the pad; a fan configured to send air into the chamber; and a support body which supports the chamber so as to be able to sink in an acting direction of a load applied to the surface of the seat. The chamber includes a first region and a second region, and the first region and the second region are configured to allow subduction of the chamber independently of each other.

A conditioning system for a vehicle passenger seat and a vehicle passenger seat assembly, the system including at least one conditioning unit including a Venturi device configured to generate air flow relative to a seat element and a temperature element configured to heat or cool the Venturi device or the air flow, a temperature sensor configured to sense a temperature in relation to the at least one conditioning unit, and a controller communicatively coupled to the temperature sensor and operably coupled to the at least one conditioning unit. The controller is configured to operate in a first operating condition in which the Venturi device is activated and the temperature element is inactive to ventilate the seat, and a second operating condition in which both the Venturi device and the temperature element are activated to heat or cool the seat.

A ventilation device for a slim vehicular seat configured for easily ensuring an airflow path in the slim seat and of reducing a thickness of the slim seat to a desired extent, may include a blowing duct, which extends from a lower portion of a seat cushion, is connected to the lower end portion of a foam pad to greatly reduce the width of the space between the foam pad and a back board, making it possible to easily manufacture a slim seat in which the overall thickness of a seat back is minimized.

Provided is a conveyance seat in which a duct connected to a fan can be compactly disposed, and the fan is provided in a pan-frame-type seat cushion. The vehicle seat includes a seat cushion and a blower provided in the seat cushion. The seat cushion is provided with a plate-shaped pan frame. The blower is provided below the pan frame, a duct is connected to the blower, and an opening through which the duct extends is formed in the pan frame.

A vehicle seat air-conditioning device includes: a blower that is included in a seat; at least one of an inlet duct or an outlet duct, the inlet duct being a duct through which air is led to be drawn in from a surface of the seat by the blower, and the outlet duct being a duct through which the air led by the blower is discharged from a surface of the seat; and a controller that is electrically connected to the blower. The blower includes a current detection circuit that detects a current consumption of the blower. The controller determines whether an occupant is sitting on the seat, based on the current consumption detected by the current detection circuit.

A seat assembly is provided with a pump for a fluid system, such as an air system. The pump has a housing with a wall surrounding a recess, with the housing defining an inlet passage and an outlet passage. A diaphragm is positioned through the wall with a distal end within the recess, and with the inlet and outlet passages in fluid communication with an opening to the pumping chamber of the diaphragm. A cam is supported for movement along a path about a central axis within the recess, and is connected to the distal end region of the diaphragm. The cam alternately moves the distal end region radially outwardly from the central axis to compress the pumping chamber and provide flow to the outlet passage, and moves the distal end region radially inwardly towards the central axis to expand the pumping chamber and provide flow into the pumping chamber.

A vehicle seat comprises: a pair of opposed frames disposed opposite to and separately from each other; a pair of connecting frames disposed separately from each other in a perpendicular direction perpendicular to an opposing direction of the pair of opposed frames, the connecting frames being configured to connect the pair of opposed frames; a bridging wire disposed to bridge the pair of connecting frames; a reinforcing wire disposed to cross the bridging wire as viewed from an occupant side; and a plate-shaped plastic member configured to cover the bridging wire and the reinforcing wire at least at their crossover such that the bridging wire and the reinforcing wire are arranged to be spaced apart from and thus kept out of contact with each other, the bridging wire and the reinforcing wire being connected with the plate-shaped plastic member.
