Abstract
A supplementary heating system for open motor vehicles, such as convertibles or roadsters, supplies warm air to shoulder and neck areas of vehicle occupants sitting in the vehicle seats. For preventing comfort-reducing draft phenomena when driving slowly and when stopped in front of a traffic light in the open vehicle, each heating module assigned to a vehicle seat has a heat exchanger, an air outlet nozzle arranged downstream of the heat exchanger and having an outflow direction into the shoulder and neck area, as well as an airstream inflow opening with an inflow funnel and a fan air inflow opening which are both arranged upstream of the heat exchanger and are separated from one another.
Claims20
Supplementary heating system for open motor vehicles for supplying warm air to the shoulder and neck area of vehicle occupants sitting in vehicle seats, comprising:
- a heating module arranged on each vehicle seat, and each heating module including
- a heat exchanger,
- an air outflow nozzle arranged downstream of the heat exchanger and having an air outflow direction toward an occupant shoulder and neck area,
- an airstream inflow opening arranged upstream of the heat exchanger and having an inflow funnel exposed to aerodynamic return or reverse flow of an outside airstream, and
- a fan air inflow opening arranged upstream of the heat exchanger and separated from the airstream inflow opening.
A supplementary heating system for supplying warm air to the neck and shoulder area of a vehicle seat occupant in an open vehicle, comprising:
- a heat exchanger arranged on a vehicle seat,
- an air outflow opening downstream of the heat exchanger operable to supply air heated in the heat exchanger toward an occupant shoulder and neck area,
- an airstream inflow opening operable to communicate portions of an outside airstream in the vehicle to the heat exchanger and having an inflow funnel exposed to the outside airstream, and
- a fan operable to generate an airflow and a fan air inflow opening operable to communicate the fan airflow to the heat exchange separately from the airstream.
