Abstract

L'invention concerne un dispositif de chauffage par rayonnement comprenant une unité de protection (7) disposée en face de l'élément chauffant (5), qui comporte des ouvertures (6) par lesquelles est transmis le rayonnement émis par l'élément chauffant (5), ainsi que des unités de conductivité thermique (8) faisant saillie de la surface de l'unité de protection (7) en direction de l'élément chauffant (5), en contact avec ledit élément (5). Dans cette configuration, il n'y a pas de contact direct entre les passagers et l'élément chauffant (5), ce qui réduit les brûlures à faible température et, comme la température du corps chauffant (5) peut être réglée élevée, la température de rayonnement peut être augmentée et l'effet chauffant accru. L'unité de protection (7) est également chauffée par conduction thermique de sorte que, même à faible température ambiante, les passagers puissent se réchauffer en touchant directement l'unité de protection (7), ce qui accroît encore l'effet chauffant.
