Arrangement for ventilation of a vehicle seat

Abstract

The invention relates to an arrangement for ventilation of a vehicle seat, which arrangement comprises an air-distributing material and an electric heating element comprising at least one electrically conductive component arranged in a pattern in conjunction with at least one support, where the vehicle seat comprises a bottom part which is adapted for ventilation by blowing air in or sucking air out via at least one passage through the bottom part and on through the said air-distributing material. According to the invention, the said support, heating element and air-distributing material are manufactured as an integrated arrangement adapted for mounting in conjunction with the said vehicle seat, the said air-distributing material being designed as at least one unit which is dimensioned for mounting in a correspondingly designed cutout in the vehicle seat. By means of the invention, an improved arrangement for heating and ventilation of a seat in a vehicle is obtained.

Description

TECHNICAL FIELD [0001] The present invention relates to an arrangement for ventilation of a vehicle seat, which arrangement comprises an air-distributing material and an electric heating element comprising at least one electrically conductive component arranged in a pattern in conjunction with at least one support, where the vehicle seat comprises a bottom part which is adapted for ventilation by blowing air in or sucking air out via at least one passage through the bottom part and on through the said air-distributing material. [0002] In particular, the invention finds application in connection with ventilation of seats intended for people travelling in a vehicle. BACKGROUND ART [0003] For reasons of comfort and safety, ventilation and temperature-control of seats is utilized in vehicles, for example. Both the driver's seat and the other vehicle seats can then be adapted for ventilation by blowing air in or sucking air out by means of a fan. In the case of air being blown in, this s...

AI Technical Summary

Benefits of technology

[0015] Examples of advantages which are obtained with the present invention are cost-effective manufacture and simpler construction of a vehicle seat compared with previously known art. A particular advantage of the invention is that it can be implemented in the form of a single delivery unit which includes all the parts required for mounting in a seat, that is to say a heating element, a suitably designed air-distributing material and a support for these components. In this way, a complete, integrated delivery unit is obtained, which can be mounted in a seat during a vehicle manufacturing process. A further advantage of the invention is that this integrated delivery unit can be attached to the upper side of a seat in a simple and effective way.

[0016] It should be noted in particular that when support, heating element and air-distributing material are manufactured as an integrated arrangement adapted for mounting in conjunction with a vehicle seat, these can be designed so that the support and the air-distributing material consist either of two separate units or of one and the same unit. In the latter case, the air-distributing material is itself so rigid and strong that it can act as a support and bear the heating element. The integrated arrangement therefore comprises an air-distributing material and an electric heating element arranged in conjunction with a support which can either consist of a separate part or be the same as the air-distributing material.

[0017] In the embodiments below, which exemplify the invention, the inventive idea is shown in a few applications. In all these cases, however, the integrated unit includes air-distributing material, electric heating element and support. Whether the support and the air-distributing material consist of one and the same unit or two separate units, the integrated unit will therefore comprise on the one hand an electrically conductive component arranged in conjunction with a support and on the other hand an air-distributing material.DESCRIPTION OF FIGURES

[0018] The invention will be described below in connection with preferred illustrative embodiments and the accompanying figures, in which:

Problems solved by technology

A particular circumstance which can constitute a problem is that the abovementioned type of seat comprises a number of material layers between the comfort foam and the cover in order to bring about the desired functions of effective ventilation and effective heating.

This can in turn involve a time-consuming and expensive manufacturing procedure and result in a high price of the finished product.

A particular problem which exists in connection with heated and ventilated vehicle seats is the need to provide a cost-effective and compact delivery unit intended for mounting in a seat in connection with manufacturing a vehicle.
