道路车辆.H点测定机（HPM-II）.H点测定的规范和程序

[中文适用范围]： 本文件提供了使用 H 点机 (HPM)1) 审核车辆座椅位置的规范和程序。 HPM 是一种物理工具，用于在车辆中建立关键参考点和测量。 H 点设计工具 (HPD) 是 HPM 的简化计算机辅助设计 (CAD)2) 版本，可与 HPM 结合使用以进行本文档中指定的可选测量，或在产品过程中独立使用设计。 这些 H 点设备提供了一种对乘员座位隔间或座椅进行可靠布局和测量的方法。 本文件规定了安装 H 点机 (HPM) 以及使用 HPM 审核（验证）车辆中的关键参考点和测量值的程序。 该设备适用于指定的座位位置。 它们不应被解释为测量或指示乘员能力或舒适度的工具。 它们不适用于定义或评估临时座椅，例如折叠跳跃座椅。 [外文原描述]： This document provides the specifications and procedures for using the H-point machine (HPM)[1] to audit vehicle seating positions. The HPM is a physical tool used to establish key reference points and measurements in a vehicle. The H-point design tool (HPD) is a simplified computer-aided design (CAD)[2] version of the HPM, which can be used in conjunction with the HPM to take the optional measurements specified in this document, or used independently during product design. These H-point devices provide a method for reliable layout and measurement of occupant seating compartments or seats. This document specifies the procedures for installing the H-point machine (HPM) and using the HPM to audit (verify) key reference points and measurements in a vehicle. The devices are intended for application at designated seating positions. They are not to be construed as tools that measure or indicate occupant capabilities or comfort. They are not intended for use in defining or assessing temporary seating, such as folding jump seats. [1] All references to H-point machine or HPM in this document refer to the SAE J4002 H-point machine (HPM-II), unless otherwise noted. [2] CAD has come to encompass any software system or approach to automotive design and development, and is often used to refer to CAE (computer-assisted engineering) and CAM (computer-assisted manufacturing) software systems as well.
