摘要： A spool for a seat belt retractor has a cylindrical member with a cylindrical central portion and two end plates at opposite axial ends of the cylindrical portion. There is a channel formed in the cylindrical central portion with an outer and an inner wall and defining a path for guiding seat belt webbing. The path circumscribes the spool axis substantially over the length of the central portion of the spool in a generally smooth curve. The path has a spool entry and a spool exit portion and an acute angle subtended at the spool axis by the entry portion of the path and the exit portion of the path is approximately 90°. The spool may be hollow with a torsion bar forming the inner wall of the channel.

摘要： A teaching apparatus comprises a unitary plate member presenting a flat, impenetrable upper surface having a plurality of holes therein representing correct answer selections, for example. A pattern of projections on the surface extends upwardly therefrom and receives an instructional sheet having zones thereon for indicating answers selected in response to questions, a stylus being employed by the student to indicate each answer by pushing the stylus against the selected indicator zone. The zones and the areas of the surface therebeneath are aligned so that the stylus meets the surface but does not penetrate the sheet beneath incorrect indicator zones, whereas openings are punched in those zones representing correct answers due to the presence of the holes. The projections, either spaced apart along the boundaries of the areas or formed as a continuous grid, prevent the student from feeling the holes and thereby anticipating the correct answers, but are limited in height so that the stylus penetrates the sheet only at the correct answer zones.

摘要翻译： 一种教学装置包括一个整体的板状构件，其具有平坦的，不可穿透的上表面，其中具有多个孔，例如表示正确的答案选择。 表面上的突起图案向上延伸并接收具有其上的区域的指示板，用于指示响应于问题而选择的答案，由学生使用触控笔来指示每个答案，通过将触针推靠在所选择的指示器区上。 这些区域和其下表面的区域对准，使得触针与表面相遇，但是不穿透不正确指示器区域下方的片材，而在由于存在孔而表示正确答案的那些区域中冲孔。 这些突起沿着区域的边界分开或形成为连续的网格，防止学生感觉到洞，从而预期正确的答案，但是在高度上受到限制，以便触笔才能以正确的答案渗透到纸张上 区域。
