Claims18
A body supporting arrangement comprising:
- a. a seat back;
- b. a head rest;
- and
- c. an air delivery arrangement comprising:
- a fan that is configured to suction air from an intermediate space defined between an upper edge of the seat back and a lower edge of the head rest, the air is suctioned upwardly in a direction from an area adjacent the upper edge of the seat back to an area adjacent the lower edge of the head rest, the fan is configured to then eject the suctioned air towards a user;
- wherein the upper edge of the seat back includes a recess so that the fan can suction the air from the intermediate space even when the head rest is lowered against the upper edge of the seat back.
3 more elements
A neck warmer comprising:
- a. a fan that is configured to suction air and then eject the suctioned air towards a neck of a user;
- and
- b. a heating appliance that is configured to transfer heat to the suctioned air that is ejected towards the neck of the user,
- wherein the heating appliance is also a diffuser that is configured to deflect a stream of the air that is ejected towards the neck of the user,
- wherein a vehicle seat comprises the neck warmer, the vehicle seat comprises a seat back and a head rest,
- wherein the fan suctions the air from an intermediate space defined between the seat back and the head rest, the air is suctioned from an area adjacent the upper edge of the seat back to an area adjacent a lower edge of the head rest, and
- wherein the fan is located in the head rest, and the seat back has an upper edge that includes a recess so that the fan can suction the air from the recess when the head rest is lowered against the upper edge of the seat back.

A vehicle seat comprising:
- a. a seat back;
- b. a head rest;
- c. an intermediate space located between an upper edge of the seat back and a lower edge of the head rest;
- and
- d. a neck warmer comprising:
- i. a fan that suctions air from the intermediate space and ejects the air towards a neck of a user, the fan comprising an impeller that is located in a working space of a housing, the working space comprises an outflow opening, and
- ii. a heating appliance that transfers heat to the air that is ejected towards the neck of the user,
- wherein the heating appliance is also a diffuser that deflects and broadens out a stream of the air that is ejected towards the neck of the user,
- wherein the heating appliance comprises a plurality of heat input elements are arranged in an arc along the outflow opening, and
- wherein the upper edge of the seat back includes a recess so that the fan can suction the air from the intermediate space when the lower edge of the head rest is against the upper edge of the seat back.
