Abstract
Seat assemblies and subassemblies are disclosed. For example, a ventilation subassembly may be disclosed. The subassembly may include a trim cover with a ventilation bag or membrane fixed thereto such as by stitching or welding. The ventilation bag or membrane may be disposed adjacent to the trim cover and extend from the trim cover through one or more additional layer to a carrier such that it is configured to receive a fluid flow from a blower for ventilating an occupant adjacent to the trim cover.
Claims20
A ventilation assembly for a seat comprising:
- a trim cover configured to contact an occupant and provide ventilation from a fluid flow when assembled in a seat and during operation;
- a ventilation bag (i) defining a cavity and a channel in fluid communication with the cavity and disposed opposite the trim cover, the channel being configured to connect with a blower through one or more additional layers and (ii) fixed to the trim cover such that a fluid flow travels from the ventilation bag to the trim cover or vice versa;
- and
- a spacer fabric disposed in the cavity.
A seat subassembly comprising:
- a trim cover having an exposed surface and an unexposed surface opposite the exposed surface, the trim cover configured to provide ventilation to an occupant adjacent to the exposed surface when a fluid flow is received at the unexposed surface;
- a carrier configured to support a blower, the carrier defining an orifice for receiving the fluid flow from the blower;
- a first sheet fixed to the trim cover and between the trim cover and the carrier;
- a second sheet between the first sheet and the carrier, the second sheet sealed to the first sheet such that the first and second sheets define a cavity including a channel, the channel configured to receive a fluid flow from the blower through the orifice;
- a spacer disposed in the cavity;
- and
- one or more additional layers disposed between the second sheet and the carrier such that the channel provides a passage through the one or more additional layers wherein ventilation is provided to or from the blower through the cavity and to or from the occupant adjacent to the trim cover.
A ventilation assembly for a seat comprising:
- a trim cover;
- a carrier configured to support a blower, the carrier defining a first orifice configured to receive a fluid flow from the blower during operation;
- a cushion disposed between the trim cover and the carrier, the cushion adjacent to the carrier and defining a second orifice;
- and
- a membrane disposed between the cushion and the trim cover and extending through the second orifice, the membrane fixed to the trim cover such that the fluid flow is received or delivered through the first orifice to the trim cover and provides ventilation through the trim cover to an occupant adjacent to the trim cover during operation.
