Abstract
(EN)
A transparent canopy (7) covers an infant seated within a baby-buggy for protecting him/her from exposure to ambient-air pollution, and a powered filter-unit (9) blows filtered ambient-air into the top of the compartment (8) between the canopy (7) and the seat-unit (4). The bottom of the compartment (8) is open where a lower, apron portion (16) of the canopy (7) hangs spaced from the seated-infant's legs. Entry of polluted air via the opening is blocked by operating the powered filter-unit (9) to create positive pressure within the compartment (8) so that the filtered air flows downwardly of the infant's face and body; a mesh inset (20) in the canopy (7) gives balanced ventilation and avoids heat build-up. The seat-unit (4) involves a back panel (25) suspended by fabric sections (26-28) within a frame (5). The panel (25) can be unlatched (29) to adapt the seat-unit (4) for use as a carry-cot.
(FR)
Une capote transparente (7) couvre un enfant assis dans une poussette pour le protéger de l'exposition à la pollution de l'air ambiant, et un ensemble filtre mécanique (9) souffle de l'air ambiant filtré dans la partie supérieure du compartiment (8), entre la capote (7) et le siège (4). Le bas du compartiment (8), ouvert, prend la forme d'une partie inférieure d'un tablier (16) de capote (7) située à distance des jambes d'un enfant assis. L'entrée d'air pollué par l'ouverture est rendue impossible par le fonctionnement de l'ensemble filtre mécanique (9) afin de créer une pression positive dans le compartiment (8), de manière que l'air filtré s'écoule vers le bas depuis le visage et le corps de l'enfant. Une pièce maillée (20) intégrée à la capote (7) procure une ventilation équilibrée et évite l'accumulation de chaleur. Le siège (4) comprend un dossier (25) suspendu par des parties en tissu (26-28) dans un cadre (5). Le dossier (25) peut être déverrouillé (29) pour transformer le siège (4) en un petit lit pour enfant.
