It has now been found that a comfortable sleeping accommodation can be provided if the seat is convertible into a stretched berth which is capable of being elevated so as to allow another stretched unit to take its position underneath. A pair of such units for accommodating passengers can either be used as sequentially arranged chairs, or as parallel disposed berths, one being above the other within the same available space.

The influence of convertible seat
A convertible seat unit comprising a first chair in combination with a second chair positioned in line with same wherein said first chair comprises in combination
(a) a first seat base having projections from the framework thereof,
(b) a first back rest movably mounted on the rear portion of said first seat base so as to be capable of being reclined from an erect, sitting position into a substantially horizontal, stretched berth position,
(c) a first leg rest, mounted at the front portion of said first seat base, and capable of being moved from an unobstructive position under said first seat base into a substantially horizontal berth position, and
(d) a first supporting means of retaining and locating said first seat base both in a sitting position and alternatively in an elevated berth position which comprises a base support member having parallel, upward stretching arms containing longitudinal channels which said projections engage in a slide-able manner, and wherein said second chair comprises.
The supporting means for the present invention may include suspending devices for instance of adjustable length which enable the seat bases to be held in a low and also in a high position. It is nevertheless more advantageous and preferred to support the seat base from below, i.e. from a floor or a foundation, in both positions.
The present invention provides comfortable sitting and resting accommodation without significant reduction of the passenger carrying capacity of the craft or vehicle. Any conversion from sitting into the lying position can be simply carried out by the users themselves or quickly arranged by trained cabin staff. A further advantage is that the convertible units according to the invention can easily be arranged in compartments so that the users could leave or approach their berths without disturbing or inconveniencing other passengers who may be asleep. The chairs can be easily fitted into existing aircraft or other vehicles or transport, or any other confined place where conversion of seats into a more resting accommodation is required. It has changed the rigid and solidified form of the ordinary chair, and made it more convenient for people to travel. To a certain extent, it has guaranteed the quality of people's travel and alleviated the pain of people's journey. It is a major progress in the manufacturing technology of seats.
