Technische Universität München Summary Report Microarchitecture Space Studies Date: 12/06/99 Project: C. SpaceBed Page: C 01 KC-135 Postflight Report Contents TITLE (of Investigation): SpaceBed, Schlafkomfort in Schwerelosigkeit (sleep restraint) FLIGHT DATES: October 27th, 28th, and 29th 1999 PRINCIPAL INVESTIGATORS (titles, etc..): Technische Universität München, Thomas Dirlich CO-INVESTIGATORS (titles, ect.): Institut für Schlafmedizin und interdiziplinäre Schlafforschung Münster, Dr. Gerd Rosenberg GOAL: To test the usability of the SpaceBed in microgravity. In special the in/egress procedures, different sleeping positions, the tolerance of the one prototype to use by persons of different size, and the dynamics of the Sleepliner in mircogravity. In addition a preliminary test for the „Instiut für Schlafmedizin und interdiziplinäre Schlafforschung“ (ISIS) with the BIA device on body impedance measurement, which in combination with others is used to evaluate regeneration effectiveness in one-g. OBJECTIVE: To provide the crews of space vessels, such as the ISS, with a sleeping system which is on the one hand easy to use, hygienic, provides maximum comfort and optimal regeneration and on the other hand is minimal in weight and volume, optimizing storability and thus transport costs. INTRODUCTION: How one performs ones daily work and responsibilities depends mainly on how effective one is able to rest and regenerate. Considering the specific physiological and psychological conditions during a long term mission in space, the importance of privacy and the possibility for effective regeneration become eminent. The SpaceBed not only deals with the ergonomic and design issues of sleep and sleep restraints, but also takes into account newest knowledge and results of modern sleep science, provided by the ISIS Institute, Muenster, Germany. Using an inflatable system for the sleep restraints minimizes mass and volume. The materials used have been designed for use in the production of modern top quality sleep and bed systems. Harmlessness for the user, maximum reliability, and hygiene were crucial in their development. © 1999 all copyrights of the shown projects are with the designers and the departement for design and architecture at tu münchen
Technische Universität München Summary Report Microarchitecture Space Studies Date: 12/06/99 Project: C. SpaceBed Page: C 02 METHODS AND MATERIALS: Procedure: The SpaceBed platform was mounted at the back end of the plane next to the PHA setup. Data was gathered by a mounted camera, handheld cameras, the BIA device and questionnaires. The experiment was scheduled to be tested on the 27th and 29th, although tests were conducted on all four days. Main points of interest for the experiment were easy use, comfort issues, and the adjustability to persons of different size. Various test person conducted the following tests: 1. in/egress into/out of the strapped, legs restrained, position without a sleepliner (pict 01) 2. in/egrees into/out of the strapped position with sleepliner attached (pict 02) 3. in/egrees into/out of the zero-g, legs free, position without sleepliner (pict 03) 4. in/egrees into/out of the zero-g position with sleepliner attached (pict 04) 5. comfort adjustments and use of SpaceBed during several parabolas 6. In addition Thomas Schielke and Thomas Dirlich gathered some data on the 27th and 29th with the BIA device (pict 05). Materials: The experiment consists of four parts: A. SpaceBed: the inflatable upper body restraint B. LegRestraint: a not fully developed functional mock-up of a leg restraint C. Sleepliner: the soft light sleeping sack which is attached to SpaceBed and LegRestraint D. Experiment platform: parabola flight specific attachment area with technical equipment RESULTS: SpaceBed was tested by 16 different persons during the four days of the flight campaign. The tests went very well and the questionnaire rating the project „highly acceptable“, a 6.2 on a scale of 7.0. The analysis of the video and photographic footage shows the simplicity of use and the tolerance of the SpaceBed to users of different size. The conceptional design ideas of the project were proved as being useful. The inflatable structure of SpaceBed not only minimizes the mass and volume, but also makes in/egress even with sleepliner easy. The support of the test persons back is very good and comfortable. The spine is held in it natural position, the fluids flow freely through the body and maximum regeneration can be achieved. DISCUSSION: SpaceBed also works with the restraints not inflated, even though comfort is higher and in/egress is much easier if they are inflated properly. © 1999 all copyrights of the shown projects are with the designers and the departement for design and architecture at tu münchen

METHODS AND MATERIALS:<br />
Procedure:<br />
The <strong>Space</strong>Bed platform was mounted at the back end of the plane next to the PHA setup. Data was<br />
