摘要： There is disclosed a protective helmet having an outer shell, a lining (10) of impact resistant material, a cradle (24,26,28) of webbing extending within and fastened to the lining and an adjustable headband (42) secured to the lining. The headband comprises a rear headband member which extends adjacent a lower edge (20) along opposite sides (16) and adjacent the rear (14) of the lining and is anchored at opposite ends (52) respectively at forwardly disposed locations of the lining, and, a front headband member (44) pivotally carried at its opposite ends (60) on the rear headband member at opposite sides of the lining whereby the front headband member can be rotated between a first operative position in which it serves as part of the headband a second retracted position within the lining in which space is provided at the front of the lining to enable the helmet to be fitted to the head of a user wearing breathing apparatus over a marginal portion of said apparatus engaging the brow of the user. Also disclosed is a buckle for varying the embrace of the headband.

摘要： A helmet (10) has a visor (12) mounted on pivot posts (18) fixed to the helmet. A visor driving and latching mechanism (24) acts both to allow the wearer to move the visor (12) between its lowered and raised positions and also to hold the visor in either position. The mechanism (24) has an operating lever (22) which is pivoted to the visor (12) at a point (30) spaced from the pivot post (18). The operating lever (22) has a slightly elongated aperture (28) which receives the pivot posts (18), and a hollowed out portion (32) which receives a cam (38) fixed in relation to the pivot post (18). The operating lever (22) has a first tooth (36) which engages in a first recess (44) in the cam (38) to hold the visor (10) in its lowered position, and a second tooth (34) which engages in a second recess (42) in the cam (38) to hold the visor (12) in its raised position. To move the visor (12) from its lowered to its raised position, the wearer manually rotates the operating lever (22) in the appropriate direction. Initial rotation of the operating lever about its pivotal connection (30) to the visor (10) withdraws the first tooth (36) of the operating lever (22) from the first recess (44) in the cam (38), to release the visor (10). Further rotation of the operating lever (22) rotates the visor (10) about the pivot post (18) until the second tooth (34) reaches the second recess (42) in the cam (38), whereupon the operating lever (22) rotates about its pivotal connection (30) to the visor (10) so as to move the second tooth (34) into the second recess (42), to latch the visor in the raised position. Similarly, to move the visor (10) to its lower position, the wearer rotates the operating lever (22) in the opposite direction, to disengage the second tooth (34) from the second recess (42), to then rotate the visor (10) to the lower position and to move the first tooth back into engagement with the first recess (44). The cam (38) has compliant projections (60 and 61), a respective one of which is engaged, in each of the lowered and raised positions of the visor (10), by the tooth (34) or (36) not engaged in the corresponding recess (42 or 44) in the cam (38), and which must be compressed during the initial movement of the operating lever (22), to inhibit inadvertent release of the latching engagement of the other tooth in the recess. The helmet may be provided with twin visors, each visor having its own driving and latching mechanism, the two mechanisms being located on opposite sides of the helmet.
摘要翻译：头盔（10）具有安装在固定到头盔上的枢轴柱（18）上的遮阳板（12）。面罩驱动和闭锁机构（24）既用于允许穿戴者将遮阳板（12）在其降低和升高位置之间移动，并且还将遮阳板保持在任一位置。机构（24）具有操作杆（22），其在与枢轴柱（18）间隔开的点（30）处枢转到遮阳板（12）。操作杆（22）具有容纳枢转柱（18）的略微伸长的孔（28），以及接收相对于枢轴柱（18）固定的凸轮（38）的挖空部分（32）。操作杆（22）具有第一齿（36），该第一齿接合在凸轮（38）中的第一凹部（44）中以将遮阳板（10）保持在其降低位置，并且第二齿（34）凸轮（38）中的第二凹部（42），用于将遮阳板（12）保持在其升高位置。为了将遮阳板（12）从其降低到升高位置移动，佩戴者在适当的方向上手动地旋转操作杆（22）。操作杆围绕其枢转连接件（30）到遮阳板（10）的初始旋转将操作杆（22）的第一齿（36）从凸轮（38）中的第一凹部（44）撤回，以释放遮阳板（10）。操作杆（22）的进一步旋转围绕枢轴柱（18）旋转遮阳板（10），直到第二齿（34）到达凸轮（38）中的第二凹槽（42），于是操作杆（22）围绕其枢转连接（30）旋转到遮阳板（10），以便将第二齿（34）移动到第二凹部（42）中，以将遮阳板锁定在升高位置。类似地，为了将遮阳板（10）移动到其下部位置，穿着者沿相反方向旋转操作杆（22），以使第二齿（34）与第二凹部（42）脱离，然后旋转遮阳板 10）移动到下部位置并且使第一齿回到与第一凹部（44）接合。凸轮（38）具有柔性突起（60和61），其中相应的突出部分通过未啮合的齿（34）或（36）接合在遮阳板（10）的每个下降和升高位置中。凸轮（38）中的相应的凹槽（42或44），并且在操作杆（22）的初始运动期间必须被压缩，以防止另一个齿在凹部中的卡合接合的意外释放。头盔可以设有双面遮阳板，每个遮阳板具有自己的驱动和锁定机构，两个机构位于头盔的相对侧。

摘要： A helmet with twin visors (12, 14; 112, 114) movable between raised and lowered positions has a locking mechanism for each visor which automatically locks the visor in the raised or lowered position. An operating lever (24, 26; 126, 226) for each visor can be operated with one hand by the wearer, a single movement of the lever first releasing the locking mechanism and then moving the visor from one to the other of its raised and loweredpositions. Each locking mechanism may comprise a cam plate (28; 128, 228) fixed to the helmet shell and two pawls (40, 42; 140, 142, 240, 242) carried by the visor arm (18, 118, 216) and spring-biased to engage the cam to lock the visor in the raised or lowered position respectively. The operating lever engages the appropriate pawl to disengage it from the cam plate and rotate the visor arm, on movement of the lever in the appropriate direction. The lower position of each visor may be adjustable, for example to accommodate an oxygen mask fitted to the helmet. The mechanism may also be used on a helmet fitted with a single visor.
摘要翻译：具有在升高和降低位置之间移动的双面遮阳板（12,14; 112,114）的头盔具有用于每个面罩的锁定机构，其将遮阳板自动地锁定在升高或降低位置。用于每个遮阳板的操作杆（24,26; 126,226）可以由穿着者用一只手操作，杆的单次运动首先释放锁定机构，然后将遮阳板从其一个提升到另一个， loweredpositions。每个锁定机构可以包括固定到头盔外壳的凸轮板（28; 128,228）和由遮阳板臂（18,118,216）和弹簧支承的两个棘爪（40,42; 140,142,240,242）偏置以接合凸轮以将遮阳板分别锁定在升高或降低位置。当杠杆沿适当的方向移动时，操作杆接合适当的棘爪以使其脱离凸轮板并旋转遮阳板臂。每个遮阳板的下部位置可以是可调节的，例如以适应安装在头盔上的氧气面罩。该机构也可用于装有单个面罩的头盔上。

摘要： A helmet comprises a headshell, visor and a harness within which the head of the user is en- gagable. An auxiliary electrically operated service is provided such as a lamp or air supply operated by switch means which are actuated as the helmet is engaged on or disengaged from the head of the user. Where the service is an air supply, the switch operates a fan motor which draws air into the helmet through a filter.
